Subject: [USN-612-7] OpenSSH update
===========================================================
Ubuntu Security Notice USN-612-7 May 20, 2008
openssh update
CVE-2008-0166
===========================================================
A security issue affects the following Ubuntu releases:
Ubuntu 6.06 LTS
This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.
The problem can be corrected by upgrading your system to the
following package versions:
Ubuntu 6.06 LTS:
openssh-server 1:4.2p1-7ubuntu3.4
In general, a standard system upgrade is sufficient to effect the
necessary changes.
Details follow:
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.
Original advisory details:
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.
Updated packages for Ubuntu 6.06 LTS:
