Debian DSA-2600-1 : cups - privilege escalation

high Nessus Plugin ID 63385

Synopsis

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

Description

Jann Horn discovered that users of the CUPS printing system who are part of the lpadmin group could modify several configuration parameters with security impact. Specifically, this allows an attacker to read or write arbitrary files as root which can be used to elevate privileges.

This update splits the configuration file /etc/cups/cupsd.conf into two files: cupsd.conf and cups-files.conf. While the first stays configurable via the web interface, the latter can only be configured by the root user. Please see the updated documentation that comes with the new package for more information on these files.

Solution

Upgrade the cups packages.

For the stable distribution (squeeze), this problem has been fixed in version 1.4.4-7+squeeze2.
