GLSA-200704-20 : NAS: Multiple vulnerabilities

This script is Copyright (C) 2007-2014 Tenable Network Security, Inc.


Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200704-20
(NAS: Multiple vulnerabilities)

Luigi Auriemma has discovered multiple vulnerabilities in NAS, some of
which include a buffer overflow in the function accept_att_local(), an
integer overflow in the function ProcAuWriteElement(), and a null
pointer error in the function ReadRequestFromClient().

Impact :

An attacker having access to the NAS daemon could send an overly long
slave name to the server, leading to the execution of arbitrary code
with root privileges. A remote attacker could also send a specially
crafted packet containing an invalid client ID, which would crash the
server and result in a Denial of Service.

Workaround :

There is no known workaround at this time.

Solution :

All NAS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-libs/nas-1.8b'

Risk factor :

Critical / CVSS Base Score : 10.0
(CVSS2#AV:N/AC:L/Au:N/C:C/I:C/A:C)
