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              <= 3.0.1                 >= 3.0.2
  2  net-print/foomatic-filters      <= 3.0.1                 >= 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.
