USN-606-1: CUPS vulnerability

Releases

• Ubuntu 7.10
• Ubuntu 7.04
• Ubuntu 6.06

Packages

• cupsys -

Details

Thomas Pollet discovered that CUPS did not properly validate the size 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)

Update instructions

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

Ubuntu 7.10

• cupsys - 1.3.2-1ubuntu7.7

Ubuntu 7.04

• cupsys - 1.2.8-0ubuntu8.4

Ubuntu 6.06

• cupsys - 1.2.2-0ubuntu0.6.06.9

In general, a standard system upgrade is sufficient to effect the
necessary changes.
