After a standard system upgrade you need to restart your session to effect the necessary changes.

USN-550-1 fixed vulnerabilities in Cairo. The upstream fixes were incomplete, and under certain situations, applications using Cairo would crash with a floating point error. This update fixes the problem. We apologize for the inconvenience. Original advisory details: Peter Valchev discovered that Cairo did not correctly decode PNG image data. By tricking a user or automated system into processing a specially crafted PNG with Cairo, a remote attacker could execute arbitrary code with user privileges.
