Generic Charting
----------------
Bugzilla has a new mechanism for generating charts (graphs over time) of any
arbitrary search. This is known as "New Charts." Legacy data from the previous
charting mechanism ("Old Charts") is migrated into the "New Charts" when you
upgrade. The Old Charts mechanism remains, but is deprecated and will be
removed in a future version of Bugzilla.
Individual users can see/create charts as long as they are a member of the
group specified in the Param 'chartgroup'. Data can be collected for
personal charts every seven days (or a longer period, as set by the user).
Charts created by an administrator can be made public (visible to all). Data
is collected for administrator charts every day (or a longer period, as set
by the admin).
The data is collected by the collectstats.pl script, which an administrator
will need to arrange to be run once every day (see the manual). Chart data can
be plotted in a number of different ways, and different data sets can be
plotted on the same graph for comparison.
Please see the Known Bugs section for some important limitations relating to
access controls on charts.

built-in replication feature.
- If you have placed any comments in the localconfig file, they may be removed
by checksetup.pl.

Recommended Practice for the Upgrade Recommended Practice for the Upgrade
************************************ ************************************
As always, please ensure you have run checksetup.pl after replacing the Note About Upgrading From MySQL With ISAM Tables
files in your installation. ------------------------------------------------
As previously noted in the Dependency Requirements MySQL is now required
to be at least version 3.23.41. This implies that all tables of type ISAM will
be converted by the checksetup.pl script to MyISAM.
It is recommended that you view the sanity check page (sanitycheck.cgi) both Steps for Upgrading
before the upgrade and after running checksetup.pl after the upgrade, to see -------------------
if there are any problems with your installation.
It is also recommended that, if possible, you fix any problems you find 1) View the Sanity Check (sanitycheck.cgi) page on your installation before
immediately. Failure to do this may mean that Bugzilla will not work correctly. upgrading.
Be aware that if the sanity check page contains more errors after an upgrade,
it doesn't necessarily mean there are more errors in your database, as
additional tests are added to the sanity check over time, and it is possible
that those errors weren't being checked for in the old version.
As previously noted in the Dependency Requirements MySQL is now required to be 2) As with any upgrade it is recommended that you make a backup of the

converted by the checksetup.pl script to MyISAM. As with any upgrade it is
recommended to make a backup of the database, perhaps by using mysqldump.
Example: Example:
mysqldump -u root -p --databases bugs > bugs.db.backup mysqldump -u root -p --databases bugs > bugs.db.backup
3) Replace the files in your installation, or you can try to use CVS to upgrade.
The Bugzilla.org website has instructions on how to do the actual
installation.
4) Make sure that you run checksetup.pl after you install the new version.
5) View the Sanity Check page again after you run checksetup.pl.
6) It is recommended that, if possible, you fix any problems you find
immediately. Failure to do this may mean that Bugzilla will not work
correctly. Be aware that if the sanity check page contains more errors after
an upgrade, it doesn't necessarily mean there are more errors in your
database, as additional tests are added to the sanity check over time, and
it is possible that those errors weren't being checked for in the old
version.
Outstanding Issues
******************
These are known problems with the release that we think you should know about.
They each have a bug number for http://bugzilla.mozilla.org/
- If at any time you upgraded from a version of Bugzilla between 2.17.4 -
2.17.7 to either 2.18rc3 or 2.19.1, you must manually fix your New Charts in
order for them to work. See the following link for instructions on how to do
this: https://bugzilla.mozilla.org/show_bug.cgi?id=276237#c18
If you are using 2.18rc3, but did not upgrade from version 2.17.4 or newer,
then you don't need to do this.
- bug 37765: If you use an MTA other than sendmail (such as Postfix, Exim,
etc.) you MUST turn on the "sendmailnow" parameter or Bugzilla will not send
e-mail correctly.
- bug 276230: The support for restricting access to particular Categories of
New Charts is not complete. You should treat the 'chartgroup' Param as the
only access mechanism available. However, additionally, charts migrated from
Old Charts will be restricted to the groups that are marked MANDATORY for
the corresponding Product. There is currently no way to change this
restriction, and the groupings will not be updated if the group configuration
for the Product changes.
- bug 69621: If you rename or remove a keyword that is in use on bugs, you will
need to rebuild the "keyword cache" by running sanitycheck.cgi and choosing
the option to rebuild the cache when it asks. Otherwise keywords may not show
up properly in search results.
- (No Bug Number) If you have a lot of non-ASCII data in your Bugzilla (for
example, if you use a translation of Bugzilla), don't enable the XS::Stash
option when you install the Template Toolkit, or your Bugzilla installation
may become slow. This problem is fixed in a not-yet-released version of the
Template Toolkit (after 2.14).
- bug 266579: Users may be able to circumvent not having "canconfirm" privileges
in some circumstances. This is fixed starting with 2.19.3, but will not
be fixed in any 2.18 release, as the changes require to fix it are quite
large.
- bug 99215: Attachment changes have no mid-air collision detection, unlike bug
changes.
- bug 57350: Searching using the "commenter is" option may be VERY slow. Note
that searching for "field: comment, changed by: user@domain.com" is fast,
though.
- bug 151509: Using the boolean chart option "contains the string" with the
"flag name" field or certain other fields will cause Bugzilla to emit an
error.
- bug 225042: If sendmail dies while you are marking a bug as a duplicate,
the duplicates table can become corrupted.
- bug 234159: Bugzilla may sometimes send multiple notices in one email.
- bug 237107: If you search for attachment information using the Boolean Charts
at the bottom of the Advanced Query page, bugs without attachments will not
show up in the result list.
Security Fixes In 2.18 Releases
*******************************
Version 2.18
------------
Summary: XSS in Internal Error messages in Bugzilla 2.16.7 and 2.18rc3
CVE Name: CAN-2004-1061
Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=272620
Details:
It is possible to send a carefully crafted URL to Bugzilla designed to
trigger an error message. The Internal Error message includes javascript code
which displays the URL the user is visiting. The javascript code does not
escape the URL before displaying it, allowing scripts contained in the URL to
be executed by the browser. Many browsers do not allow unescaped URLs to be
sent to a webserver (thus complying with RFC 2616 section 2.3.1 and RFC 2396
section 2.4.3), and are thus immune to this issue.
Browsers which are known to be immune: Firefox 1.0, Mozilla 1.7.5,
Camino 0.8.2, Netscape 7.2, Safari 1.2.4
Browsers known to be susceptible: Internet Explorer 6 SP2,
Konqueror 3.2
Browsers not listed here have not been tested.
Version 2.18.1
--------------
Two security issues were fixed in Bugzilla 2.18.1, neither of them
critical.
See http://www.bugzilla.org/security/2.16.8/ for details.
Detailed Version-To-Version Release Notes
*****************************************
*********************************************************
*** USERS UPGRADING FROM ALL VERSIONS PRIOR TO 2.16.7 ***
*********************************************************
*** Security fixes ***
- It is possible to send a carefully crafted HTTP POST message to
process_bug.cgi which will remove keywords from a bug even if you don't have
permissions to edit all bug fields (the "editbugs" permission). Such changes
are reported in "bug changed" email notifications, so they are easily
detected and reversed if someone abuses it. Users are now prevented from
making changes to keywords if they do not have editbugs privileges. (bug
252638)
*** Bug fixes of note ***
- Enforce a minimum of 10 minutes between attempts to reset a password, so
we don't mailbomb the user if someone submits the form many times in a
row. (bug 250897)
- Put products in alphabetical order on the create attachment status page.
(bug 251427)
- Specify MyISAM as the table type when creating new tables. MySQL 4.1 and
up default to InnoDB, which doesn't support some of the indexing methods
that we use. (bug 263165)
*********************************************************
*** USERS UPGRADING FROM ALL VERSIONS PRIOR TO 2.16.6 ***
*********************************************************
*** Security fixes ***
- If Bugzilla is configured to hide entire products from some users, both
duplicates.cgi and the form for mass-editing a list of bugs in buglist.cgi
can disclose the names of those hidden products to such users.
(bugs 234825 and 234855)
- Several administration CGIs echo invalid data back to the user without
escaping it. (bug 235265)
- A user with privileges to grant membership to any group (i.e. usually an
administrator) can trick editusers.cgi into executing arbitrary SQL.
(bug 244272)
*** Bug fixes of note ***
- Allow XML import to function when there are regexp metacharacters in product
names (bug 237591)
- Allow the bug_email.pl contrib script to work with useqacontact (bug 239912)
- Improve the error message used by checksetup.pl when the MySQL requirements
are not met (bug 240228)
- Elimnate the warning in checksetup.pl about the minimum sendmail version (bug
240060)
- $webservergroup now defaults to group 'apache' in new installations (bug
224477)
- Correct a situation where a bugmail message could be sent twice to a user
being added to the CC list if the address was entered in a different case
than the user registered with. (bug 117297)
- Various documentation updates
*********************************************************
*** USERS UPGRADING FROM ALL VERSIONS PRIOR TO 2.16.4 ***
*********************************************************
*** Bug fixes of note ***
- Fix a "used only once" warning that ocurred only in perl 5.00503
(bug 2321691)
- When a user is creating a new account and enters an invalid email
address, the error page sent the "Content-type" header twice, causing
the second one to be visible at the top of the page.
(bug 137121)
- An HTML encoding issue which only affected Internet Explorer was
corrected in the "Change several bugs at once" page.
(bug 181106)
- During initial setup, using invalid characters in the administrator
password would present an error message stating your password was
too long or too short instead of telling you it had invalid
characters.
(bug 166755)
- When a user reset their own password via an emailed token, the new
password in the first field would be accepted if the second password
field was left blank.
(bug 123077)
- Reopening bugs from the "change several bugs at once" page now works.
(bug 95430)
- Fix a regression in xml.cgi caused by the previous bugfix for MySQL
SUM() changes. The original fix didn't work properly either.
(bug 225474)
- No longer use server push with the "Safari" browser, which claims to
use the Mozilla layout engine but doesn't.
(bug 188712)
- Creating a shadow database no longer fails with taint mode errors.
(bug 227510)
- If you change your cookiepath setting at some stage (because you have
moved the directory Bugzilla resides on your webserver), users can
have login cookies with the old cookiepath, and their browsers will
send multiple logincookies. Bugzilla now uses the first rather than
the last in order to get the most specific cookie which will be the
correct one.
(bug 121419)
- Fixed a regression caused by the previous DBD::mysql fixes, that
caused older versions of DBD::mysql to break due to not supporting
the new DBI syntax.
(bug 224815)
- Bugzilla no longer sends out invalid dates for cookie expiry. This
bug had no known user visible ramifications.
(bug 228706)
- Update the shadow database parameters description to tell the user
about permissions requirements for creating a shadow database.
(bug 227513)
- Various documentation updates.
*********************************************************
*** USERS UPGRADING FROM ALL VERSIONS PRIOR TO 2.16.3 ***
*********************************************************
*** SECURITY ISSUES RESOLVED ***
- A user with 'editproducts' privileges (i.e. usually an administrator)
can select arbitrary SQL to be run by the nightly statistics cron job
(collectstats.pl), by giving a product a special name.
(bug 214290)
- A user with 'editkeywords' privileges (i.e. usually an administrator)
can inject arbitrary SQL via the URL used to edit an existing keyword.
(bug 219044)
- When deleting products and the 'usebuggroups' parameter is on, the
privilege which allows someone to add people to the group which is
being deleted does not get removed, allowing people with that
privilege to get that privilege for the next group that is created
which reuses that group ID. Note that this only allows someone who
had been granted privileges in the past to retain them.
(bug 219690)
- If you know the email address of someone who has voted on a secure
bug, you can access the summary of that bug even if you do not have
sufficient permissions to view the bug itself.
(bug 209376)
*** Bug fixes of note ***
Perl 5.8.0 Compatibility fixes:
- Two taint errors were fixed, one in process_bug.cgi, and
another in post_bug.cgi.
(bugs 220332 and 177828)
MySQL 4.0 Compatibility fixes:
- A cosmetic fix was applied to votes.cgi (if there were no
votes, the "0" was not displayed) due to a change in semantics
in SUM() in MySQL 4.0.
(bug 217422)
DBD::mysql > 2.1026 Compatibility fixes:
- DBD::mysql versions after 2.1026 return the table list quoted, which
broke the existing "table exists" check in checksetup.pl, which caused
the second and subsequent attempts to run checksetup.pl to fail.
(bug 212095)
Miscellaneous bug fixes:
- A Mozilla-specific reference was removed from one of the report
templates.
(bug 221626)
- It was possible to enter a situation where you were unable to get to
editparams.cgi to turn the shutdownhtml param back off after you
turned it on when Apache was configured to run Bugzilla in suexec
mode.
(bug 213384)
- The processmail rescanall task would not send e-mails about more than
one bug to the same address.
(bug 219508)
- If Bugzilla hadn't been accessed in the last hour when the
collectstats.pl or whineatnews.pl cron jobs ran, the versioncache
would get recreated with the file owner being the user the cron job
was running as (usually not the webserver user), causing subsequent
access to Bugzilla by the webserver to fail until the permissions were
fixed. Now if versioncache isn't readable when accessing from the
webserver, we pretend it doesn't exist and recreate it again.
(bug 160422)
- The 'sendmailnow' param is now on by default in new installations
(this does not affect existing installations).
(bug 146087)
- The 008filter.t test would fail if you had multiple language packs
installed. It now properly tests all of the installed language packs.
(bug 203318)
- A few minor documentation changes were committed.
*********************************************************
*** USERS UPGRADING FROM ALL VERSIONS PRIOR TO 2.16.2 ***
*********************************************************
*** SECURITY ISSUES RESOLVED ***
- A cross site scripting (XSS) vulnerability was fixed in which bug
summaries were not properly filtered when a user viewed a dependency graph
allowing JavaScript to be embedded on that page.
(bug 192661)
- Several XSS vulnerabilities were fixed in which user
input was not escaped when being displayed. A new
test has been added to warn about unfiltered data in template
files (t/008filter.t).
(bug 192677)
- An issue was fixed in which the QA contact was still treated as the QA
contact even after the 'useqacontact' setting was turned off. This also
allowed the QA contact to edit the security groups and view secured bugs that
he/she was allowed to access prior to the 'useqacontact' setting being
deactivated.
(bug 194394)
- Fixed a situation where an attacker (with local access to the webserver)
could overwrite any file on the webserver to which the webserver user
has write access by creating appropriately named symbolic links in the
data and webdot directories (world-writable in many configurations).
Bugzilla now uses File::Temp to create secure temporary files. File::Temp
is part of the Perl distribution for Perl 5.6.1 and later, but if you're
using an older version of Perl you'll need to install it with CPAN.
(bug 197153)
** IMPORTANT CHANGES ***
- New module requirement: File::Temp, as mentioned above.
*** Bug fixes of note ***
- An issue was fixed in which administrator rights could be removed from an
administrator who deleted a product while the 'usebuggroups' setting is
activated.
(bug 157704)
- Fixed an issue in which importxml.pl would fail the test suite when running
under perl 5.8.0 with the optional XML::Parse module.
(bug 172331)
- There was previously a bug in CGI.pl in which the following warning
would be given under certain conditions:
"Character in "c" format wrapped at CGI.pl..."
This is now fixed. In some cases the warning was filling up web server log
files.
(bug 194125)
- Fixed a bug in which long component names (in excess of 50 characters) would
be accepted when creating the component but would cause problems when trying
to use that component on a bug because it would get truncated. It is now no
longer possible to create components with names in excess of 50 characters.
(bug 197180)
- Fixed a bug in checksetup.pl in which permissions were not being fixed
on the 'data/comments' file, the quip file.
(bug 160279)
*****************************************************************
*** USERS UPGRADING FROM 2.16.1 OR EARLIER, 2.14.4 OR EARLIER ***
*****************************************************************
*** SECURITY ISSUES RESOLVED ***
- Fixed a cross site scriptability issue in quips. This is only a problem
if quips with HTML could have been inserted into your quips files. Bugzilla
has not allowed this since 2.12.
(bug 179329)
- checksetup.pl will now attempt to prevent access to "editor backups" of
localconfig.
(bug 186383)
- collectstats.pl no longer makes data/mining (which contains graphing
information) world writeable.
(bug 183188)
***********************************************
*** USERS UPGRADING FROM 2.16.0 OR EARLIER ***
***********************************************
*** SECURITY ISSUES RESOLVED ***
- Apostrophes were not properly handled in email addresses. This was a
regression introduced in 2.16. It is not known whether this was
exploitable.
(bug 165221)
See also next major section.
*** Bug fixes of note ***
- The VERSION cookie which allowed the previously entered version of a product
to be remembered was not correctly set. It was only set as a session
cookie, and under some circumstances could interfere with other cookies
(such as the login information) send at the same time.
(bug 160227)
- importxml.pl would fail if the versioncache needed to be updated.
(bug 164464)
- Bug changes going through intermediate pages would munge fields with
multiple fields, such as CCs.
(bug 161203)
- On failure in template->new, Bugzilla will now die rather than futilely
attempt to use an error template.
(bug 166023)
- Fixed a problem where checksetup had problems converting old installations
that didn't have a duplicates table.
(bug 151619)
- Fixed a problem that caused taint errors when viewing or editing user
preferences with Perl 5.005 and Template 2.08.
(bug 160710)
See also next section.
******************************************************
*** USERS UPGRADING FROM 2.16.0, 2.14.3 OR EARLIER ***
******************************************************
*** SECURITY ISSUES RESOLVED ***
- When a new product is added to an installation with 47 groups or more and
"usebuggroups" is enabled, the new group will be assigned a groupset bit
using Perl math that is not exact beyond 2^48. This results in the new
group being defined with a "bit" that has several bits set. As users are
given access to the new group, those users will also gain access to
spurious lower group privileges. Also, group bits were not always reused
when groups were deleted.
(bug 167485)
- The email interface had another insecure single parameter system call. This
could potentially allow arbitrary shell commands to be run. This file is
not supported at this time, but as long as we knew about the problem, we
couldn't overlook it.
(bug 163024)
*** Bug fixes of note ***
- The email interface was broken. This was a 2.14.3 regression. This file
is not supported at this time, but as long as we knew about the problem, we
couldn't overlook it.

*** USERS UPGRADING FROM 2.14.5 OR EARLIER ***
***********************************************
*** SECURITY ISSUES RESOLVED ***
- The bug reporter could set the priority even when
'letsubmitterchoosepriority' was off.
(bug 63018)
- Most CGIs are now templatised. This helps to make it
easier to remember to HTML filter values and easier to spot
when they are not, preventing cross site scripting attacks.
(bug 86168)
- Most CGIs now run in taint mode. This helps to prevent
failure to validate errors.
(bug 108982)
*** IMPORTANT CHANGES ***
- 2.16 introduces "templatisation", a new feature that allows
administrators to easily customise the HTML output (the "look and feel")
of Bugzilla without altering Perl code. Bugzilla uses the
"Template Toolkit" for this. Please see the "Template Customisation"
section of the Bugzilla Guide for more details.
Administrators who ran the 2.15 development version and customised
templates should check the templates are still valid, as file names
and file paths have changed.
Most output is now templatised. This process will be complete next
milestone.
For speed, compiled templates are cached on disk. If you modify the
templates, the toolkit will normally detect the changes, and recompile the
changed templates.
Adding new directories anywhere inside the template directory may cause
permission errors if you don't have a webservergroup specified in
localconfig. If you see these, rerun checksetup.pl as root. If you do not
have root access, or cannot get someone who does to do this for you, you can
rename the data/template directory to data/template.old (or any other name
Bugzilla doesn't use). Then rerun checksetup.pl to regenerate the compiled
templates.
(bug 86168, 97832)
- Administrators can now configure maximum attachment sizes. These
should remain below the maximum size for your MySQL server, or you
will get obscure MySQL errors if you attach a bigger attachment.
To find out the current size attachment that MySQL can accept, type
the command 'mysqladmin variables' and find out the value of the
'max_allowed_packet' varible in bytes.
To change the maximum size that MySQL can accept you can alter this
variable in your 'my.cnf' file.
(bug 91664)
- Perl 5.004 is no longer supported because the Template Toolkit
requires 5.005.
(bug 97721)
- New module requirements: Text::Wrap, Template [requires AppConfig],
File::Spec.
(bugs 97784, 84338, 103778)
- The index page is now a CGI instead of an HTML page. You should remove
any existing index.html file and make sure your web server allows index.cgi
to be the default page in a directory. If you are not able to do that you
can instead set index_html in the 'localconfig' file to 1 and checksetup.pl
will create a redirect page for you.
(bug 80183)
- It is now recommended that administrators run "processmail rescanall"
after upgrading to 2.16 or beyond.
This will send out notification emails for changes that were
made but not emailed, due to Bugzilla bugs. All known
causes of this have been fixed in this version (bug 104589 and 99519).
It is also recommended that this be run nightly to avoid
lengthy delays in future if this problem reoccurs.
(bug 106377)
- In parallel with templatisation, a lot of changes have been made to the HTML
output of the Bugzilla CGIs. This could break code that attempts to parse
such code. For example, this breaks mozbot.
(no bug number)
- The "HTML template" parameters (headerhtml, bodyhtml, footerhtml,
errorhtml, bannerhtml, blurbhtml, mostfreqhtml, entryheaderhtml) have now
been moved to Template Toolkit templates. If you have modified these
parameters you will need to make corresponding changes to the corresponding
templates. Your old parameter values will be moved to a file called
old-params.txt by checksetup.pl.
The old parameters correspond to files in template/en/default as follows:
headerhtml: global/header.html.tmpl
footerhtml: global/footer.html.tmpl
bannerhtml: global/banner.html.tmpl
blurbhtml: global/banner.html.tmpl
mostfreqhtml: reports/duplicates*.html.tmpl
entryheaderhtml: bug/create/user-message.html.tmpl
(bug 140437)
*** Other changes of note ***
- The query page has been redesigned for better user friendliness.
(bug 98707)
- Users can now change their email account.
(bug 23067)
- "Dependent Bug Changed" notification emails now contain the
dependent bug's summary and URL.
(bug 28736, 113383)
- Bugs with severity "critical", "blocker", and "enhancement" are
visually differentiated on bug lists for browsers with sufficient
CSS support.
(bug 28884)
- Bugzilla now has a sidebar for the Mozilla browser.
(bug 37339)
- A link to just created attachments now appears in notification
email.
(bug 66651)
- Comments now have numbers and can be referenced with
autohyperlinkifying similar to bugs.
(bug 71840)
- The attachment system has been rewritten, supporting new
"attachment statuses" (like keywords, but for attachments),
the ability to obsolete attachments, edit attachment MIME type,
and edit whether the attachment is a patch.
(bugs 84338, 75176)
- syncshadowdb now supports a configurable temp file location,
and properly shuts down Bugzilla while running.
(bug 75840)
- Dependency tree now lets you exclude resolved bugs and bugs
below a specified depth.
(bugs 83058)
- The "strictvaluechecks" parameter has gone away. These checks
are now always done.
(bug 119715)
- The midair collision page now shows all changes since the bug
page was loaded, not just the last one.
(bug 108312)
- Added support for making dependency graphs with 'dot', which
is better at creating complex graphs than 'webdot'.
(bug 120537)
*** Bug fixes of note ***
- Bugzilla scripts are now usually not terminated when the browser
window they are running in is closed. This caused hard to
reproduce bugs.
(bug 104589)
- On browsers that "reflow" the page, large component / milestone /
version fields were extremely slow to reflow when you altered
the product field.
(bug 96534)
- The selection in the component / milestone / version fields is
no longer lost when you change the selection in the product
field or use the back/forward buttons in your browser to return
to the page.
(bug 97966)
- You could not reverse dependencies in one step.
(bug 82143)
- Mass reassignment of non-open bugs will no longer reopen them.
(bug 30731)
- Attempting to bulk change no bugs will now give a user-friendly
error message.
(bug 90333)
- If you make a change to a bug where you only add yourself to CC,
email notifications are now properly sent out for MySQL 3.23.
(bug 99519)
- Bug entry now properly validates the data it has been sent.
(bug 107743)
- Midair collision checks will now properly work in all situations
where dependencies have changed.
(bug 73502)
- Browsers can no longer corrupt the params file if they use the "wrong"
end-of-line markers.
(bug 92500)
- The MySQL port defined in localconfig is now properly honoured.
(bug 98368)
- Apostrophes in component/milestone/version names no longer cause
a problem on the query page.
(bug 30689/42810)
- File attachment comments will now wrap.
(bug 52060)
- Saved queries are no longer mangled if you need to log in again,
for example if you had cookies off.
(bug 38835)
- Bug counts (on reports.cgi) were very slow if you had to
count a lot of bugs.
(bug 63249)
- 2.14 introduced options to let people see a bug when their name
is on it but who aren't in the groups the bug is restricted
to. These only allowed the people to view the bugs directly,
and not see them on buglists and receive email about them.
(bugs 95024, 97469)
- A new 'cookiepath' parameter on editparams.cgi allows multiple
Bugzilla installations to exist on one host without problems.
(bug 19910)
- whineatnews.pl now respects the 'sendmailnow' parameter.
(bug 52782)
- The query page came up even when Bugzilla was shut down.
(bug 121747)
- Quicksearch gave a weird error message when Bugzilla was
shut down.
(bug 121741)
- Operating system detection fixes.
(bugs 92763, 135666)
- QA contacts now receive emails when a new bug is created and
their only email preference was being added or removed from QA.

*** USERS UPGRADING FROM 2.14.2 OR EARLIER ***
***********************************************
*** SECURITY ISSUES RESOLVED ***
- Basic maintenance on contrib/bug_email.pl and
contrib/bugzilla_email_append.pl which also fixes a
possible security hole with a misuse of a system() call.
These files are not supported at this time, but as long
as we knew about the problem, we couldn't overlook it.
(bug 154008)
*** Bug fixes of note ***
- The fix for bug 130821 in 2.14.2 broke being able to sort
bug lists on more than one field. buglist.cgi now allows
you to sort on more than one field again.
(bug 152138)
***********************************************
*** USERS UPGRADING FROM 2.14.1 OR EARLIER ***
***********************************************
*** SECURITY ISSUES RESOLVED ***
- queryhelp.cgi no longer shows confidential products to
people it shouldn't.
(bug 126801)
- It was possible for a user to bypass the IP check by
setting up a fake reverse DNS, if the Bugzilla web server
was configured to do reverse DNS lookups. Apache is not
configured as such by default. This is not a complete
exploit, as the user's login cookie would also need to
be divulged for this to be a problem.
(bug 129466)
- In some situations the data directory became world writeable.
(bug 134575)
- Any user with access to editusers.cgi could delete a user
regardless of whether 'allowuserdeletion' is on.
(bug 141557)
- Real names were not HTML filtered, causing possible cross
site scripting attacks.
(bug 146447, 147486)
- Mass change would set the groupset of every bug to be the
groupset of the first bug.
(bug 107718)
- Some browsers (eg NetPositive) interacted with Bugzilla
badly and could have various form problems, including
removing group restrictions on bugs.
(bug 148674)
- It was possible for random confidential information to be
divulged, if the shadow database was in use and became
corrupted.
(bug 92263)
- The bug list sort order is now stricter about the SQL it will accept,
ensuring you use correct column name syntax. Before this, there were
some syntax checks, so it is not known whether this problem was
exploitable.
(bug 130821)
********************************************
*** USERS UPGRADING FROM 2.14 OR EARLIER ***
********************************************
The 2.14.1 release fixes several security issues that became
known to us after the Bugzilla 2.14 release.
*** SECURITY ISSUES RESOLVED ***
- If LDAP Authentication was being used, Bugzilla would allow
you to log in as anyone if you left the password blank.
(bug 54901)
- It was possible to add comments or file a bug as someone else
by editing the HTML on the appropriate submission page before
submitting the form. User identity is checked now, and the
form values suggesting the user are now ignored.
(bug 108385, 108516)
- The Product popup menu on the show_bug form listed all
products, even if the user didn't have access to all of them.
It now only shows products the user has access to (and the
product the bug is in, if the user is viewing it because of
some other override).
(bug 102141)
- If a user had any blessgroupset privileges (the ability to
change only specific privileges for other users), it was
possible to change your own groupset (privileges) by
altering the page HTML before submitting on editusers.cgi.
(bug 108821)
- An untrusted variable was echoed back to user in the HTML
output if there was a login error while editing votes.
(bug 98146)
- buglist.cgi had an undocumented parameter that allowed you
to pass arbitrary SQL for the "WHERE" part of a query.
This has been disabled.
(bug 108812)
- It was possible for a user to send arbitrary SQL by inserting
single quotes in the "mybugslink" field in the user
preferences.
(bug 108822)
- buglist.cgi was not validating that the field names being
passed from the "boolean chart" query form were valid field
names, thus allowing arbitrary SQL to be inserted if you
edited the HTML by hand before submitting the form.
(bug 109679)
- long_list.cgi was not validating that the bug ID parameter
was actually a number, allowing arbitrary SQL to be inserted
if you edited the HTML by hand.
(bug 109690)
********************************************
*** USERS UPGRADING FROM 2.12 OR EARLIER ***
********************************************
*** SECURITY ISSUES RESOLVED ***
- Multiple instances of unauthorised access to confidential
bugs has been fixed.
(bug 39524, 39526, 39527, 39531, 39533, 70189, 82781)
- Multiple instances of untrusted parameters not being
checked/escaped was fixed. These included definite security
holes.
(bug 38854, 38855, 38859, 39536, 87701, 95235)
- After logging in passwords no longer appear in the URL.
(bug 15980)
- Procedures to prevent unauthorised access to confidential
files are now simpler. In particular the shadow directory
no longer exists and the data/comments file no longer needs
to be directly accessible, so the entire data directory can
be blocked. However, no changes are required here if you
have a properly secured 2.12 installation as no new files
must be protected.
(bug 71552, 73191)
- If they do not already exist, checksetup.pl will attempt to
write Apache .htaccess files by default, to prevent
unauthorised access to confidential files. You can turn this
off in the localconfig file.
(bug 76154)
- Sanity check can now only be run by people in the 'editbugs'
group. Although it would be better to have a separate
group, this is not possible until the limitation on the
number of groups allowed has been removed.
(bug 54556)
- The password is no longer stored in plaintext form. It will
be eradicated next time you run checksetup.pl. A user must
now change their password via a password change request that
gets validated at their e-mail account, rather than have it
mailed to them.
(bug 74032)
- When you are using product groups and you move a bug between
products (single or mass change), the bug will no longer be
restricted to the old product's group (if it was) and will
be restricted to the new product's group.
(bug 66235)
- There are now options on a bug to choose whether the
reporter, and CCs can access a bug even if they aren't in
groups the bug it is restricted to.
(bug 39816)
- You can no longer mark a bug as a duplicate of a bug you
can't see, and if you mark a bug a duplicate of a bug
the reporter cannot see you will be given options as to
what to do regarding adding the reporter of the resolved
bug to the CC of the open bug.
(bug 96085)
*** IMPORTANT CHANGES ***
- Bugzilla 2.14 no longer supports old email tech. Upon
upgrading, all users will be moved over to new email tech.
This should speed up upgrading for installations with
a large number of bugs.
(bug 71552)
- There is new functionality for people to see why they are
receiving notification mails.
Previously, some people filtered old email tech
notifications depending on whether they were in the To or the
CC header, in order to get a limited way of determining why
they were receiving the notification for filtering purposes.
Existing installations will need to make changes to support
this feature. The receive reasons can be added to the
notifications as a header and/or in the body. To add these
you will need to modify your newchangedmail parameter on
editparams.cgi, either by resetting it or appropriately
modifying it. The header value is specified by
%reasonsheader% and the body by %reasonsbody%. For example,
the new default parameter is:
--------------------------------------------------
From: bugzilla-daemon
To: %to%
Subject: [Bug %bugid%] %neworchanged%%summary%
X-Bugzilla-Reason: %reasonsheader%
%urlbase%show_bug.cgi?id=%bugid%
%diffs%
%reasonsbody%
--------------------------------------------------
(bug 26194)
- Very long fields (especially multi-valued fields like keywords,
CCs, dependencies) on bug activity and notifications previously
could get truncated, resulting in useless notifications and data
loss on bug activity. Now the multi-valued fields only show
changes, and very big changes are split into multiple lines.
Where data loss has already occurred on bug activity, it is
indicated using question marks.
(bug 55161, 92266)
- Previously, when a product's voting preferences changed all
votes were removed from all the bugs in the product. Also,
when a bug was moved to another product, all of its votes
were removed. This no longer occurs.
Instead, if the action would leave one or more bugs with
greater than the maximum number of votes per person per bug,
the number of votes will be reduced to the maximum. The
person will still be notified of this as before.
If the action would leave a user with more votes in a product
than is allowed, the limit will be breached so as to not lose
votes. However the user will not be able to update their
votes except to fix this situation. No further action is taken
in this version to make sure that the user does this.
(bug 28882, 92593)
*** Other changes of note ***
- Groups can now be marked inactive, so you can't add a new
restriction on that group to a bug, while leaving bugs that
were previously restricted on that group alone.
(bug 75482)
- backdoor.cgi has been removed from the installation. It was
old code that was Netscape-specific and its name was scaring
people.
(bug 87983)
- You can now add or remove from CC on the bulk change page.
(bug 12819)
- New users created by administrators are now automatically
inserted into groups according to the group's regular
expression. Administrators must edit the user in a second
step to override these choices. Previously the
administrator specified these explicitly which could lead
to incorrect settings.
(bug 45164)
- The userregexp of system groups can now be edited without
resorting to direct database access.
(bug 65290)
*** Bug fixes of note ***
- The bug list page was sometimes bringing up a not logged in
footer when the user was logged in and the installation was
using a shadow database.
(bug 47914)
- You can now view the bug summary in your browser title for
a group-restricted bug if you have proper permissions.
(bug 71767)
- Quick search for search terms did not work in IE5.
This has been worked around.
(bug 77699)
- Quick search for search terms crashed NN4.76/4.77 for Unix.
This has been worked around.
(bug 83619)
- Queries on bugs you have commented on using the "added
comment" feature should be a lot faster and not time out
on large installations due to the addition of an index.
(bug 57350)
- You can now alter group settings on bulk change for groups
that aren't on for all bugs or off for all bugs.
(bug 84714)
- New bug notifications now include the CC and QA fields.
(bug 28458)
- Bugzilla is now more Windows friendly, although it is still
not an official platform.
(bug 88179, 29064)
- Passwords are now encrypted using Perl's encrypt function.
This makes Bugzilla more portable to more operating systems.
(bug 77473)
- Bugzilla didn't properly shut down when told to - some
queries could still be sent to the database.
(bug 95082)
********************************************
*** USERS UPGRADING FROM 2.10 OR EARLIER ***
********************************************
*** SECURITY ISSUES RESOLVED ***
- Some security holes have been fixed where shell escape characters
could be passed to Bugzilla, allowing remote users to execute
system commands on the web server.
*** IMPORTANT CHANGES ***
- There is now a facility for users to choose the sort of
notifications they wish to receive. This facility will
probably be improved in future versions.
(bug 17464)
- "Changed" will no longer appear on the subject line of
change notification emails. Because of this, you should
change the subject line in your 'changedmail' and
'newchangedmail' params on editparams.cgi. The subject
line needs to be changed from
Subject: [Bug %bugid%] %neworchanged% - %summary%
to:
Subject: [Bug %bugid%] %neworchanged%%summary%
or whatever is appropriate for the subject you are using
on your system. Note the removal of the " - " in the
middle.
(bug 29820)
*** Other changes of note ***
- Bug titles now appear in the page title, and will hence
display in the user's browser's bookmarks and history.
(bug 22041)
- Edit groups functionality (editgroups.cgi).
(bug 25010)
- Support for moving bugs to other Bugzilla databases.
(bug 36133)
- Bugzilla now can generate a frequently reported bugs list
based on what duplicates you receive.
(bug 25693)
- When installing Bugzilla fresh, the administrator account is
now created in checksetup.pl.
(bug 17773)
- Stored queries now show their name above the bug list, which
helps the user when they have multiple bug lists in multiple
browser windows. It also appears in the page title, and will
hence display in the user's browser's bookmarks and history.
(bug 52228)
- All states and resolutions can now be collected for charting.
(bug 6682)
- A new search-engine-like "quick search" feature appears on
the front page to try and making searching easier.
(bug 69793)
- Querying on dependencies now works in the advanced query
section of the query page.
(bug 30823)
- When a bug is marked as a duplicate, the reporter of the
resolved bug is automatically added to the CC list of the
open bug.
(bug 28676)
*** Bug fixes of note ***
- Notification emails will now always be sent to QA contacts.
Previously they wouldn't if you were using new email tech.
(bug 30826)
- When marking a bug as a duplicate, the duplicate stamp marked
on the open bug will no longer be written too early (such as
on mid-air collisions).
(bug 7873)
- Various bug fixes were made to the initial assignee and QA
of a component. It is no longer possible to enter an
invalid address. They will also now properly update when
a user's email address is changed. Sanity check will now
check these.
(bug 66876)
- Administrators can no longer create an email accounts that do
not match the global email regular expression parameter.
Previously this could occur and would cause sanity check
errors.
(bug 32971)
- The resolution field can no longer become empty when the
bug is resolved. This occurred because of midair collisions.
(bug 49306)
