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.
