software projects. The following security issue has been discovered
in Bugzilla:

* Attachment editing was vulnerable to a cross-site request forgery.

Vulnerability Details

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.
