Security Advisory for Bugzilla v2.13 and older
30 August 2001
Bookmark and Share

All users of Bugzilla, the bug-tracking system from mozilla.org, are strongly recommended to update to version 2.14.

Bugzilla 2.14 is a general security update, but not all of the security issues are serious.

Serious issues include:

* Multiple instances where data on "confidential" bugs could be obtained by valid users of the system who are not authorized to.
* Multiple instances of security holes where parameters were not being checked/escaped properly.

There are many patches that need to be applied to properly close these holes, so they are not included here. If you will not be upgrading your system to 2.14 and instead wish to apply these patches to your existing system, please consult the bug reports on bugzilla.mozilla.org for the bug numbers listed below, where you can obtain the patches attached to those bugs.

Complete bug reports for all bugs can be obtained by visiting the following URL: http://bugzilla.mozilla.org/show_bug.cgi?id=XXXXX where you replace the XXXXX at the end of the URL with a bug number as listed below. You may also enter the bug numbers in the "enter a bug#" box on the main page at http://bugzilla.mozilla.org/ or in the footer of any other page on bugzilla.mozilla.org.


- Multiple instances of unauthorized 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 unauthorized 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 unauthoried 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 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, assignee, QA 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)
