GLSA-200802-07 : Pulseaudio: Privilege escalation

This script is Copyright (C) 2008-2014 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-200802-07
(Pulseaudio: Privilege escalation)

Marcus Meissner from SUSE reported that the pa_drop_root() function
does not properly check the return value of the system calls setuid(),
seteuid(), setresuid() and setreuid() when dropping its privileges.

Impact :

A local attacker could cause a resource exhaustion to make the system
calls fail, which would cause Pulseaudio to run as root. The attacker
could then perform actions with root privileges.

Workaround :

There is no known workaround at this time.

Solution :

All Pulseaudio users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=media-sound/pulseaudio-0.9.9'

Risk factor :

High / CVSS Base Score : 7.2
