Ubuntu 6.06 LTS : openssh update (USN-612-7)

Ubuntu Security Notice (C) 2008-2013 Canonical, Inc. / NASL script (C) 2008-2013 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related patches.

Description :

USN-612-2 introduced protections for OpenSSH, related to the OpenSSL
vulnerabilities addressed by USN-612-1. This update provides the
corresponding updates for OpenSSH in Ubuntu 6.06 LTS. While the
OpenSSL in Ubuntu 6.06 is not vulnerable, this update will block weak
keys generated on systems that may have been affected themselves.

A weakness has been discovered in the random number generator used by
OpenSSL on Debian and Ubuntu systems. As a result of this weakness,
certain encryption keys are much more common than they should be, such
that an attacker could guess the key through a brute-force attack
given minimal knowledge of the system. This particularly affects the
use of encryption keys in OpenSSH, OpenVPN and SSL certificates.

Solution :

Update the affected packages.

Risk factor :

High / CVSS Base Score : 7.8
(CVSS2#AV:N/AC:L/Au:N/C:C/I:N/A:N)
CVSS Temporal Score : 6.4
(CVSS2#E:F/RL:OF/RC:C)
Public Exploit Available : true
