critical Nessus Plugin ID 87237

Synopsis

The remote Ubuntu host is missing a security update.

Description

Michal Kowalczyk 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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution
