Emmanuel Bouillon discovered that CUPS did not properly handle certain
Internet Printing Protocol (IPP) packets. A remote attacker could use this
flaw to cause a denial of service or possibly execute arbitrary code. In
the default installation in Ubuntu 8.04 LTS and later, attackers would be
isolated by the CUPS AppArmor profile.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 9.10
Ubuntu 8.04
Ubuntu 6.06
Ubuntu 10.10
Ubuntu 10.04

In general, a standard system update will make all the necessary changes.
