Ubuntu 10.04 LTS / 11.04 / 11.10 / 12.04 LTS : samba vulnerability (USN-1434-1)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

Ivano Cristofolini discovered that Samba incorrectly handled some
Local Security Authority (LSA) remote procedure calls (RPC). A remote,
authenticated attacker could exploit this to grant administrative
privileges to arbitrary users. The administrative privileges could be
used to bypass permission checks performed by the Samba server.

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 package.

Risk factor :

Medium / CVSS Base Score : 6.5
(CVSS2#AV:N/AC:L/Au:S/C:P/I:P/A:P)
CVSS Temporal Score : 5.7
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : false
