Subject: [USN-550-2] Cairo regression
===========================================================
Ubuntu Security Notice USN-550-2 December 10, 2007
libcairo regression
https://launchpad.net/bugs/NNNNNN
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 7.04
Ubuntu 7.10
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 7.04:
libcairo2 1.4.2-0ubuntu1.2
Ubuntu 7.10:
libcairo2 1.4.10-1ubuntu4.2
After a standard system upgrade you need to restart your session to effect
the necessary changes.
Details follow:
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.
Updated packages for Ubuntu 7.04:
