<title>Pulseaudio: Privilege escalation</title>
<synopsis>

with escalated privileges.
</synopsis>
<product type="ebuild">pulseaudio</product>
<announced>February 13, 2008</announced>
<revised>February 13, 2008: 01</revised>
<bug>207214</bug>
<access>local</access>
<affected>
<package name="media-sound/pulseaudio" auto="yes" arch="*">
<unaffected range="ge">0.9.9</unaffected>
<vulnerable range="lt">0.9.9</vulnerable>
</package>
</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>
