Date Reported:

07 Sep 2011

Affected Packages:

bcfg2

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 640028.
In Mitre's CVE dictionary: CVE-2011-3211.

More information:

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.

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.

For the testing distribution (wheezy), this problem has been fixed in version 1.1.2-2.

For the unstable distribution (sid), this problem has been fixed in version 1.1.2-2.

We recommend that you upgrade your bcfg2 packages.
