Synopsis
========
Local files on the server can be attached to a bug (making them publicly
visible) when importing bugs with --attach_path
Background
==========
Bugzilla is a Web-based bug-tracking system, used by a large number of
software projects.
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 alwaysignored.
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.)
Affected packages
=================
Bugzilla in test and stable.
Resolution
==========
All bugzilla users should upgrade to the latest available version:
# scribe update
# cast -c bugzilla
