3.0.4, 3.1.4, and 2.22.4 Security Advisory

   August 12, 2008

Summary
=======

Bugzilla is a Web-based bug-tracking system, used by a large number of
software projects.

This advisory covers a security issue that has recently been fixed
in the Bugzilla code:

* Local files on the server can be attached to a bug (making them
  publicly visible) when importing bugs with --attach_path

All affected installations are encouraged to upgrade as soon as possible.

Vulnerability Details
=====================

Class:       Directory Traversal
Versions:    2.22.1 - 2.22.4, 2.23.3 and higher
Description: When importing bugs using importxml.pl, the --attach_path
             option can be specified, pointing to the directory where
             attachments to import are stored. If the XML file being
             read by importxml.pl contains a malicious
             <data encoding="filename">../relative_path/to/local_file</data>
             node, the script follows this relative path and attaches the
             local file pointed by it to the bug, making the file public.
             The security fix makes sure the relative path is always
             ignored.
             Most Bugzilla installations will not be vulnerable, as
             they do not use --attach_path with importxml.pl.
             (In fact, most installations don't use importxml.pl at all.)
