This script is Copyright (C) 2009-2014 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-200903-06
(nfs-utils: Access restriction bypass)

Michele Marcionelli reported that nfs-utils invokes the hosts_ctl()
function with the wrong order of arguments, which causes TCP Wrappers
to ignore netgroups.

Impact :

A remote attacker could bypass intended access restrictions, i.e. NFS
netgroups, and gain access to restricted services.

Workaround :

There is no known workaround at this time.

Solution :

All nfs-utils users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-fs/nfs-utils-1.1.3'

Risk factor :

High / CVSS Base Score : 7.5
