GLSA 200409-24: Foomatic: Arbitrary command execution in foomatic-rip filter

http://security.gentoo.org/

Severity:	high
Title:	Foomatic: Arbitrary command execution in foomatic-rip filter
Date:	09/20/2004
Bugs:	#64166
ID:	200409-24

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	Architecture(s)
net-print/foomatic	<= 3.0.1	>= 3.0.2	All supported architectures
net-print/foomatic-filters	<= 3.0.1	>= 3.0.2	All 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.
