Remote host has weak Debian OpenSSH Keys in ~/.ssh/authorized_keys

This script is Copyright (C) 2008-2015 Tenable Network Security, Inc.

Synopsis :

The remote SSH host is set up to accept authentication with
weak Debian SSH keys.

Description :

The remote host has one or more ~/.ssh/authorized_keys
files containing weak SSH public keys generated on a Debian
or Ubuntu system.

The problem is due to a Debian packager removing nearly all
sources of entropy in the remote version of OpenSSL.

This problem does not only affect Debian : any user uploading
a weak SSH key into his ~/.ssh/authorized_keys file will
compromise the security of the remote system.

An attacker could try a brute-force attack against the remote
host and log in with these weak keys.

Solution :

Remove all the offending entries from ~/.ssh/authorized_keys

Risk factor :

Critical / CVSS Base Score : 10.0
CVSS Temporal Score : 8.3
Public Exploit Available : true
