This advisory covers one security issue that has recently been fixed in the Bugzilla code: * 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. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=476603 Vulnerability Solutions ======================= The fix for the security bug mentioned in this advisory is included in the 3.3.4 and 3.2.3 releases. Upgrading to one of these releases will protect your installation from possible exploits of this issue.
