GLSA-200704-22 : BEAST: Denial of Service

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-200704-22
(BEAST: Denial of Service)

BEAST, which is installed as setuid root, fails to properly check
whether it can drop privileges accordingly if seteuid() fails due to a
user exceeding assigned resource limits.

Impact :

A local user could exceed his resource limit in order to prevent the
seteuid() call from succeeding. This may lead BEAST to keep running
with root privileges. Then, the local user could use the 'save as'
dialog box to overwrite any file on the vulnerable system, potentially
leading to a Denial of Service.

Workaround :

There is no known workaround at this time.

Solution :

All BEAST users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-sound/beast-0.7.1'

Risk factor :

High / CVSS Base Score : 7.2
