GLSA-200704-03 : OpenAFS: Privilege escalation

This script is Copyright (C) 2007-2015 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-200704-03
(OpenAFS: Privilege escalation)

Benjamin Bennett discovered that the OpenAFS client contains a design
flaw where cache managers do not use authenticated server connections
when performing actions not requested by a user.

Impact :

If setuid is enabled on the client cells, an attacker can supply a fake
FetchStatus reply that sets setuid and root ownership of a file being
executed. This could provide root access on the client. Remote attacks
may be possible if an attacker can entice a user to execute a known
file. Note that setuid is enabled by default in versions of OpenAFS
prior to 1.4.4.

Workaround :

Disable the setuid functionality on all client cells. This is now the
default configuration in OpenAFS.

Solution :

All OpenAFS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=net-fs/openafs-1.4.4'

Risk factor :

High / CVSS Base Score : 7.5
