Mandriva Linux Security Advisory : pulseaudio (MDVSA-2009:152)

high Nessus Plugin ID 39871

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

A vulnerability has been found and corrected in pulseaudio :

Tavis Ormandy and Julien Tinnes of the Google Security Team discovered that pulseaudio, when installed setuid root, does not drop privileges before re-executing itself to achieve immediate bindings. This can be exploited by a user who has write access to any directory on the file system containing /usr/bin to gain local root access. The user needs to exploit a race condition related to creating a hard link (CVE-2009-1894).

This update provides fixes for this vulnerability.

Solution

Update the affected packages.
