Tuesday, Nov 2nd, 2010Summary ======= 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: * 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. Vulnerability Details ===================== Class: HTTP Response Splitting Versions: Every Version Before 3.2.9, 3.4.9, 3.6.3, 4.0rc1 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 to inject both headers and content to any browser that supported "Server Push" (mostly only Gecko-based browsers like Firefox).
