<access>local</access>
<affected>

<background>
<p>
Pulseaudio is a networked sound server with an advanced plugin system.

<description>
<p>
Marcus Meissner from SUSE reported that the pa_drop_root() function
does not properly check the return value of the system calls setuid(),
seteuid(), setresuid() and setreuid() when dropping its privileges.
</p>
</description>
<impact type="high">
<p>
A local attacker could cause a resource exhaustion to make the system
calls fail, which would cause Pulseaudio to run as root. The attacker
could then perform actions with root privileges.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Pulseaudio users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-sound/pulseaudio-0.9.9&quot;</code>
</resolution>
