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.
