Package        : rssh
Vulnerability  : programming error
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2006-1320
Debian Bug     : 346322

Russ Allbery discovered that rssh, a restricted shell, performs
insufficient checking of incoming commands, which might lead to a bypass
of access restrictions.

For the stable distribution (sarge) this problem has been fixed in
version 2.2.3-1.sarge.2.

For the unstable distribution (sid) this problem has been fixed in
version 2.3.0-1.1.

We recommend that you upgrade your rssh package.

- --------------------

wget url
        will fetch the file for you

        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
