3.0.10, 3.2.5, 3.4.4, and 3.5.2 Security Advisory

Sunday, January 31, 2010
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.

CVE Number:  CVE-2009-3989

Issue 2
-------
Class:       Information leak
Versions:    3.3.1 to 3.4.4, 3.5.1, 3.5.2
Description: When moving a bug from one product to another, an intermediate
             page is displayed letting you select the groups the bug should
             be restricted to in the new product. 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.
