===========================================================
Ubuntu Security Notice USN-265-1	     March 23, 2006
libcairo vulnerability
CVE-2006-0528
===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 5.10 (Breezy Badger)

The following packages are affected:

libcairo2

The problem can be corrected by upgrading the affected package to
version 1.0.2-0ubuntu1.1. In general, a standard system upgrade is
sufficient to effect the necessary changes.

Details follow:

When rendering glyphs, the cairo graphics rendering library did not
check the maximum length of character strings. A request to display
an excessively long string with cairo caused a program crash due to an
X library error.

Mike Davis discovered that this could be turned into a Denial of
Service attack in Evolution. An email with an attachment with very
long lines caused Evolution to crash repeatedly until that email was
manually removed from the mail folder.

This only affects Ubuntu 5.10. Previous Ubuntu releases did not use
libcairo for text rendering.
