Test ID:1.3.6.1.4.1.25623.1.0.840341
Category:Ubuntu Local Security Checks
Title:Ubuntu: Security Advisory (USN-612-10)
Summary:The remote host is missing an update for the 'openvpn' package(s) announced via the USN-612-10 advisory.
Description:Summary:
The remote host is missing an update for the 'openvpn' package(s) announced via the USN-612-10 advisory.

Vulnerability Insight:
USN-612-3 addressed a weakness in OpenSSL certificate and key
generation in OpenVPN by adding checks for vulnerable certificates
and keys to OpenVPN. A regression was introduced in OpenVPN when
using TLS with password protected certificates which caused OpenVPN
to not start when used with applications such as NetworkManager.

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.

Affected Software/OS:
'openvpn' package(s) on Ubuntu 7.04, Ubuntu 7.10, Ubuntu 8.04.

Solution:
Please install the updated package(s).

CVSS Score:
5.0

CVSS Vector:
AV:N/AC:L/Au:N/C:P/I:N/A:N
