TITLE:
Ubuntu update for pulseaudio

SECUNIA ADVISORY ID:
SA28738

VERIFY ADVISORY:
http://secunia.com/advisories/28738/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

OPERATING SYSTEM:
Ubuntu Linux 7.10
http://secunia.com/product/16251/
Ubuntu Linux 7.04
http://secunia.com/product/14068/

DESCRIPTION:
Ubuntu has issued an update for pulseaudio. This fixes a security
issue, which can be exploited by malicious, local users to perform
certain actions with escalated privileges.

The security issue is caused due to the pulseaudio daemon failing to
check whether it has successfully dropped its privileges via
"setuid()". This can potentially be exploited to launch the daemon
with root privileges, which may allow the user to perform certain
actions as the root user.

This is related to:
SA28623

SOLUTION:
Apply updated packages.

-- Ubuntu 7.04 --
