3.2.2 and 3.3.3 Security AdvisoryMonday, Mar 30th, 2009
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: * Attachment editing was vulnerable to a cross-site request forgery. Note that this issue was only fixed for 3.2.3 and 3.3.4 even though all versions of Bugzilla are affected (see below for an explanation). All affected installations are encouraged to upgrade as soon as possible. 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. Vulnerability Solutions ======================= The fix for this issue is included in the releases. Upgrading to a release with the relevant fix will protect your installation from possible exploits of this issue. If you are unable to upgrade but would like to patch just the security vulnerability, there are patches available for the issue at the "References" URL.
