Synopsis
=======

The foomatic-rip filter in foomatic-filters contains a vulnerability which may allow arbitrary command execution on the print server.



Background
=========

Foomatic is a system for connecting printer drivers with spooler systems such as CUPS and LPD. The foomatic-filters package contains wrapper scripts which are designed to be used with Foomatic.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-print/foomatic = 3.0.2
2 net-print/foomatic-filters = 3.0.2
-------------------------------------------------------------------
2 affected packages on all of their supported architectures.
-------------------------------------------------------------------

Description
==========

There is a vulnerability in the foomatic-filters package. This vulnerability is due to insufficient checking of command-line parameters and environment variables in the foomatic-rip filter.

Impact
=====

This vulnerability may allow both local and remote attackers to execute arbitrary commands on the print server with the permissions of the spooler (oftentimes the "lp" user).

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All foomatic users should upgrade to the latest version:

# emerge sync

# emerge -pv ">=net-print/foomatic-3.0.2"
# emerge ">=net-print/foomatic-3.0.2"

PLEASE NOTE: You should update foomatic, instead of foomatic-filters. This will help to ensure that all other foomatic components remain functional.
