of PNG images. A local attacker, and a remote attacker if printer
sharing is enabled, could send a crafted file and cause a denial of
service or possibly execute arbitrary code as the non-root user in
Ubuntu 6.06 LTS and 7.04. In Ubuntu 7.10, attackers would be isolated
by the AppArmor CUPS profile. (CVE-2008-1722).
