Debian DSA-2302-1 : bcfg2 - missing input sanitization

high Nessus Plugin ID 56116

Language:

Synopsis

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

Description

It has been discovered that the Bcfg2 server, a configuration management server for Bcfg2 clients, is not properly sanitizing input from Bcfg2 clients before passing it to various shell commands. This enables an attacker in control of a Bcfg2 client to execute arbitrary commands on the server with root privileges.

Solution

Upgrade the bcfg2 packages.

For the oldstable distribution (lenny), this problem has been fixed in version 0.9.5.7-1.1+lenny1.

For the stable distribution (squeeze), this problem has been fixed in version 1.0.1-3+squeeze1.
