Debian DSA-2007-1 : cups - format string vulnerability

medium Nessus Plugin ID 44988

Language:

Synopsis

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

Description

Ronald Volgers discovered that the lppasswd component of the cups suite, the Common UNIX Printing System, is vulnerable to format string attacks due to insecure use of the LOCALEDIR environment variable. An attacker can abuse this behaviour to execute arbitrary code via crafted localization files and triggering calls to _cupsLangprintf().
This works as the lppasswd binary happens to be installed with setuid 0 permissions.

Solution

Upgrade the cups packages.

For the stable distribution (lenny), this problem has been fixed in version 1.3.8-1+lenny8.
