Package        : openssh
Vulnerability  : remote memory overwrite, key exchange problem
Type           : remote exploit
Debian-specific: no

This upload fixes:

 1. Prior versions of OpenSSH are vulnerable to a remote arbitrary
    memory overwrite attack which may eventually lead into a root
    exploit.  No exploit program is known yet but expected to come up
    soon.

 2. CORE-SDI has described a problem with regards to RSA key exchange
    and a Bleichenbacher attack to gather the session key from an ssh
    session.

We recommend you upgrade your openssh package immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.
