Ubuntu 13.10 : openssh vulnerability (USN-2014-1)

Ubuntu Security Notice (C) 2013-2016 Canonical, Inc. / NASL script (C) 2013-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Markus Friedl discovered that OpenSSH incorrectly handled memory when
the AES-GCM cipher was used. A remote authenticated attacker could use
this issue to execute arbitrary code as their user, possibly bypassing
shell or command restrictions.

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.

Solution :

Update the affected openssh-server package.

Risk factor :

Medium / CVSS Base Score : 6.0
(CVSS2#AV:N/AC:M/Au:S/C:P/I:P/A:P)
CVSS Temporal Score : 5.2
(CVSS2#E:ND/RL:OF/RC:C)
