Ubuntu Security Notice USN-1194-1
22nd August, 2011
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
An attacker could send crafted input to Foomatic and cause it to run programs as the "lp" user.
- foomatic-filters - OpenPrinting printer support - filters
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
The problem can be corrected by updating your system to the following package version:
- Ubuntu 11.04:
- foomatic-filters 4.0.7-0ubuntu1.1
- Ubuntu 10.10:
- foomatic-filters 4.0.5-0ubuntu3.1
- Ubuntu 10.04 LTS:
- foomatic-filters 4.0.4-0ubuntu1.1
- Ubuntu 8.04 LTS:
- foomatic-filters 3.0.2-20071204-0ubuntu2.3
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
