========================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.04
- Ubuntu 10.10
- Ubuntu 10.04 LTS
- Ubuntu 8.04 LTS

Summary:

An attacker could send crafted input to Foomatic and cause it to run
programs as the "lp" user.

Software Description:
- foomatic-filters: OpenPrinting printer support - filters

Details:

It was discovered that the foomatic-rip Foomatic filter incorrectly
handled command-line options. An attacker could use this flaw to cause
Foomatic to execute arbitrary code as the "lp" user.

In the default installation, attackers would be isolated by the CUPS
AppArmor profile.

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.04:
foomatic-filters 4.0.7-0ubuntu1.1
