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.
