2.14.5
Release Notes
2.14.5 Release Notes
The 2.14.5 release fixes some security issues in 2.14.4. Please see the
upgrade procedure below for details on how to upgrade to 2.14.5.
*** PLEASE NOTE ***: The Bugzilla team no longer supports the 2.14 branch.
This is the last point release of 2.14, there will not be any more. From
this point onwards if any additional security holes are discovered, you
will need to upgrade to a newer branch (i.e. 2.16.2 or later) or you will
be on your own in patching your installation.
Regarding security issues, please note that the 2.16 line (2.16.2 was
released simultaneous with 2.14.5) incorporates various rearchitectures
that make failure-to-validate and failure-to-filter errors harder to
insert and easier to spot. In particular this means there may be holes
in the 2.14 line that have not been discovered, yet are fixed in the
2.16 line.
**************************
*** ABOUT THIS VERSION ***
**************************
Bug numbers referenced in this document are all on
bugzilla.mozilla.org unless otherwise specified.
*** Recommended Practice For The Upgrade ***
As always, please ensure you have run checksetup.pl after
replacing the files in your installation.
It is recommended that you view the sanity check page
(sanitycheck.cgi) both 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 you can, you immediately fix
any problems you find. 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 likely
those errors weren't being checked for in the old version.
Failure to do this may mean that bugzilla will not
work correctly.
Administrators must make sure that certain files are
inaccessible or confidential information might become
available to enterprising individuals. This includes the
localconfig file and the entire data directory. Please
see the Bugzilla Guide for more information.
*** Deprecated Features ***
- The 2.16 line is the last stable release that will work with
MySQL version 3.22. Bugzilla in CVS requires at least
version 3.23.6. (bug 87958)
- The 2.16 line is the last stable release to support the
"shadow" database. The replacement (using MySQL's built-in
replication) is not present in 2.14.5 or 2.16.2, but we
expect that very few sites use this feature, so we are not
planning a transition period. If this would cause a problem
for you, please comment on the below bug. (bug 124589)
- Placing comments in localconfig is deprecated. If you have
done this, they will likely get nuked with some post-2.16
version of Bugzilla, as checksetup.pl will likely
automatically rewrite localconfig to automatically get the
latest instructional comments. (bug 147776)
*** Outstanding Issues Of Note ***
These issues may have been fixed in later stable or development
versions of Bugzilla. If you are interested in tracking these
bugs, please see the bug report numbers listed to find out the
status of the fix for these bugs, or to obtain a patch that can
fix the problem on your installation.
- Bug counts (on reports.cgi) can be very slow if you have to
count a lot of bugs. In this case the connection can time
out before the page finishes loading. Extending the cgi
timeout on your web server might help this situation.
(bug 63249)
- Renaming or removing keywords that are in use will not update
the "keyword cache" on bugs, and queries on keywords may not work
properly, until you rebuild the cache on the sanity check page
(sanitycheck.cgi). The changer will receive a warning to do
this when altering the keyword.
(bug 69621)
- Email notifications will not work out of the box if you are
using Postfix, Exim or possibly other non-SendMail mail
transfer agents, as Bugzilla sends mail by default in
"deferred" mode using the "-ODeliveryMode=deferred" command
line option, which needs to be supported by the sendmail
program. To fix this, you can turn on the "sendmailnow"
parameter on the Edit Parameters page (editparams.cgi).
(bug 37765)
- The new 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 only allow people to view bugs if they know the bug number.
It still will not show up in these people's buglists and
they will not receive email about changes to the bugs.
(bugs 95024, 97469)
- Users behind rotating transparent proxies or otherwise having
an IP that changes each URL fetch will find they need to log in
regularly.
(bug 20122)
- If you search on any CC or added comments, as well as at least
one other of CC, added comments, assignee, reporter, etc, then
the search can be very slow. This is because of limitations of
the MySQL optimiser.
(bug 96101)
- Querying on CC takes too long on big databases.
(bug 127200)
- The email preferences option "Priority, status, severity, and/or milestone
changes" does not actually report status changes. You can however use the
option "The bug is resolved or verified" to achieve part of this.
(bug 130821)
***********************************************
*** USERS UPGRADING FROM 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 2.14.3 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.
(bug 160631)
***********************************************
*** 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)
*******************************************
*** USERS UPGRADING FROM 2.8 OR EARLIER ***
*******************************************
Release notes were not compiled for versions of Bugzilla before
2.12.
The file 'UPGRADING-pre-2.8' contains instructions you may
need to perform in addition to running 'checksetup.pl' if you
are running a pre 2.8 version.
