Insight
Insight
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. Affected: 2008.1, 2009.0, 2009.1
