Mandriva Linux Security Advisory : pulseaudio (MDVSA-2009:152)
High Nessus Plugin ID 39871
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionA 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.
SolutionUpdate the affected packages.
