Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related
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.
This vulnerability only affects operating systems which (like Ubuntu)
are based on Debian. However, other systems can be indirectly affected
if weak keys are imported into them.
We consider this an extremely serious vulnerability, and urge all
users to act immediately to secure their systems.
Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
Update the affected openssh-client and / or openssh-server packages.
