CVE request for bcfg2 (remote root)

Hi,

A bug report in Debian has come to light for which I can find no other
information, and therefore I do not believe it has a CVE - but probably
should.

From http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=640028 :

"All released stable versions of the bcfg2-server contain several cases
where data from the client is used in a shell command without properly
escaping it first. The 1.2 prerelease series has been fixed.

"At least the SSHbase plugin has been confirmed as being exploitable.
This is a remote root hole, which requires that the SSHbase plugin is
enabled and that the attacker has control of a bcfg2 client machine."

A patch for the problem has been commited [1] upstream and backported [2] to
the 1.1 series.
