Debian DSA-1811-1 : cups, cupsys - null ptr dereference

medium Nessus Plugin ID 38992

Synopsis

The remote Debian host is missing a security-related update.

Description

Anibal Sacco discovered that cups, a general printing system for UNIX systems, suffers from NULL pointer dereference because of its handling of two consecutive IPP packets with certain tag attributes that are treated as IPP_TAG_UNSUPPORTED tags. This allows unauthenticated attackers to perform denial of service attacks by crashing the cups daemon.

Solution

Upgrade the cups/cupsys packages.

For the oldstable distribution (etch), this problem has been fixed in version 1.2.7-4+etch8 of cupsys.

For the stable distribution (lenny), this problem has been fixed in version 1.3.8-1+lenny6 of cups.
