Ubuntu 6.06 LTS / 7.10 / 8.04 LTS / 8.10 : nfs-utils vulnerability (USN-687-1)

Ubuntu Security Notice (C) 2008-2016 Canonical, Inc. / NASL script (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing one or more security-related
patches.

Description :

It was discovered that nfs-utils did not properly enforce netgroup
restrictions when using TCP Wrappers. Remote attackers could bypass
the netgroup restrictions enabled by the administrator and possibly
gain access to sensitive information.

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 nfs-common, nfs-kernel-server and / or nhfsstone
packages.

Risk factor :

High / CVSS Base Score : 7.5
(CVSS2#AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVSS Temporal Score : 6.5
(CVSS2#E:ND/RL:OF/RC:C)
Public Exploit Available : true
