4.5.3, 4.4.3, 4.2.8, and 4.0.12

Summary
=======

Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issue has been discovered
in Bugzilla:

* The login form had no CSRF protection, meaning that an attacker could
force the victim to log in using the attacker's credentials.

* Dangerous control characters can be inserted into Bugzilla, notably
into bug comments, which can then be used to execute local commands.

All affected installations are encouraged to upgrade as soon as
possible.


Vulnerability Details
=====================

Class:       Cross-Site Request Forgery
Versions:    Bugzilla 2.0 to 4.4.2, 4.5.1 to 4.5.2
Fixed In:    4.4.3, 4.5.3
Description: The login form had no CSRF protection, meaning that
 an attacker could force the victim to log in using the
 attacker's credentials. If the victim then reports a new
 security sensitive bug, the attacker would get immediate
 access to this bug.
 Due to changes involved in the Bugzilla API, this fix is
 not backported to the 4.0 and 4.2 branches, meaning that
 Bugzilla 4.0.12 and older, and 4.2.8 and older, will
 remain vulnerable to this issue.
