Ubuntu Update for libcairo regression USN-550-2

Summary
Ubuntu Update for Linux kernel vulnerabilities USN-550-2
Solution
Please Install the Updated Packages.
Insight
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.
Affected
libcairo regression on Ubuntu 7.04 , Ubuntu 7.10
