Summary ======= Bugzilla is a Web-based bug-tracking system, used by a large number of software projects. This advisory covers two security issues that have recently been fixed in the Bugzilla code: + Some files stored on the web server are not correctly protected against external access and can be viewed from a web browser. + Restricting a bug to a group while moving the bug to another product has no effect if the group is not used by both products. The bug may become public if no other group restriction applies. All affected installations are encouraged to upgrade as soon as possible. Vulnerability Details ===================== Issue 1 ------- Class: Information leak Versions: all versions before 3.0.11, 3.2.6, 3.4.5, and 3.5.3 Description: Bugzilla allows web browsers to serve the contents of files in the CVS/, contrib/, docs/en/xml/, and t/ directories, as well as the old-params.txt file. These files do not contain sensitive data by default, but custom installations may have added scripts or files into these directories which contain e.g. passwords or some other sensitive information. We now forbird access to these directories from a web browser as a preventive measure.

However, a regression in the 3.4.x series made it ignore all groups which are not available in both products. As a workaround, you had to move the bug to the new product first and then restrict it to the desired groups, in two distinct steps, which could make the bug temporarily public. Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=532493 CVE Number: CVE-2009-3387 Vulnerability Solutions ======================= The fixes for all of the security bugs mentioned in this advisory are included in the 3.0.11, 3.2.6, 3.4.5, and 3.5.3 releases.
