USN-2838-1: cups-filters vulnerability

16 December 2015

cups-filters could be made to run programs as the lp user if it processed a specially crafted print job.




Adam Chester discovered that the cups-filters foomatic-rip filter
incorrectly stripped shell escape characters. A remote attacker could
possibly use this issue to execute arbitrary code as the lp user.

Update instructions

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

Ubuntu 15.10
Ubuntu 15.04
Ubuntu 14.04

In general, a standard system update will make all the necessary changes.
