Ubuntu 14.04 LTS / 16.04 LTS / 16.10 / 17.04 : samba vulnerability (USN-3353-2) (Orpheus' Lyre)

Ubuntu Security Notice (C) 2017 Canonical, Inc. / NASL script (C) 2017 Tenable Network Security, Inc.


Synopsis :

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

Description :

USN-3353-1 fixed a vulnerability in Heimdal. This update provides the
corresponding update for Samba.

Jeffrey Altman, Viktor Dukhovni, and Nicolas Williams discovered that
Samba clients incorrectly trusted unauthenticated portions of Kerberos
tickets. A remote attacker could use this to impersonate trusted
network servers or perform other attacks.

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 samba-libs package.

Risk factor :

Medium / CVSS Base Score : 6.8
(CVSS2#AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 5.0
(CVSS2#E:U/RL:OF/RC:C)
