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

medium Nessus Plugin ID 38992
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


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.


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.
