Synopsis

The remote Debian host is missing a security-related update.

Description

Tavis Ormandy and Julien Tinnes discovered that the pulseaudio daemon does not drop privileges before re-executing itself, enabling local attackers to increase their privileges.

Solution

Upgrade the pulseaudio packages.

The old stable distribution (etch) is not affected by this issue.

For the stable distribution (lenny), this problem has been fixed in version 0.9.10-3+lenny1.
