3.2.2 and 3.3.3 Security Advisory
March 30, 2009
Bugzilla is a Web-based bug-tracking system, used by a large number of
This advisory covers one security issue that has recently been
fixed in the Bugzilla code:
* Attachment editing was vulnerable to a cross-site request forgery.
Note that this issue was only fixed for 3.2.3 and 3.3.4 even though
all versions of Bugzilla are affected (see below for an explanation).
All affected installations are encouraged to upgrade as soon as
Class: Cross-Site Request Forgery
Versions: Every version before 3.2.3 or 3.3.4
Fixed In: 3.2.3, 3.3.4
Description: Attachment editing was vulnerable to a cross-site request
forgery, because it did not validate that calls to
attachment.cgi actually came from Bugzilla.
Bugzilla now generates a token that is validated when
an attachment is edited. Unfortunately, a fix for this issue
was only possible for 3.2.3 and 3.3.4. Fixing it on earlier
branches was not possible as attachment timestamps are not
available to generate and validate tokens.
The fix for the security bug mentioned in this advisory is included
in the 3.3.4 and 3.2.3 releases. Upgrading to one of these releases
will protect your installation from possible exploits of this issue.
Full release downloads, patches to upgrade Bugzilla from previous
versions, and CVS upgrade instructions are available at:
