3.2.8, 3.4.8, 3.6.2, and 3.7.3 Security Advisory
Tuesday, Nov 2nd, 2010
Summary
=======
Bugzilla is a Web-based bug-tracking system used by a large number of
software projects. The following security issues have been discovered
in Bugzilla:
* There is a way to inject both headers and content to users, causing
a serious Cross-Site Scripting vulnerability.
* It was possible to see graphs from Old Charts even if you did not
have access to a particular product, and you could browse a
particular URL to see all product names.
* YUI 2.8.1, which shipped with Bugzilla starting with 3.7.x,
contained a security vulnerability. The version of YUI shipped
with Bugzilla 4.0rc1 and above has been updated to 2.8.2.
All affected installations are encouraged to upgrade as soon as
possible.

Fixed In: 3.2.9, 3.4.9, 3.6.3, 4.0rc1
Description: By inserting a certain string into a URL, it was possible
