The following security issues have been discovered in Bugzilla: * The 'realname' parameter is not correctly filtered on user account creation, which could lead to user data override. * Several places were found in the Bugzilla code where cross-site scripting attacks could be used to access sensitive information. * Private comments can be shown to flagmail recipients who aren't in the insider group * Specially formatted values in a CSV search results export could be used in spreadsheet software to attack a user's computer. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Class: Unauthorized Account Creation Versions: 2.23.3 to 4.0.14, 4.1.1 to 4.2.10, 4.3.1 to 4.4.5, 4.5.1 to 4.5.5 Fixed In: 4.0.15, 4.2.11, 4.4.6, 4.5.6 Description: An attacker creating a new Bugzilla account can override certain parameters when finalizing the account creation that can lead to the user being created with a different email address than originally requested.

All releases fix several security issues found since the last release. Bugzilla 4.4.6 is our latest stable release. Bugzilla 4.4.6, 4.2.11 and 4.0.15 are security updates for the 4.4, 4.2, and the 4.0 branches, respectively. Note that 4.5.6 is an unstable development release and should not be used in production environments. We are not yet feature-frozen at this time so the features you see in 4.5.5 might not accurately represent the behavior that 5.0 will have. Note that when Bugzilla 5.0 is released (likely later this year), the Bugzilla 4.0.x series will reach end of life. If you are using that series, we encourage you to upgrade to 4.4.6 now.

Defect Tracking Systems allow individuals or groups of developers to keep track of outstanding bugs in their product effectively. Most commercial defect-tracking software vendors charge enormous licensing fees. Despite being "free", Bugzilla has many features its expensive counterparts lack. Consequently, Bugzilla has quickly become a favorite of thousands of organizations across the globe, and is widely regarded as one of the top defect-tracking systems available.
