<title>PulseAudio: Local privilege escalation</title>
<synopsis>
A vulnerability in PulseAudio may allow a local user to execute code with
escalated privileges.
</synopsis>
<product type="ebuild">pulseaudio</product>
<announced>July 16, 2009</announced>
<revised>July 16, 2009: 01</revised>
<bug>276986</bug>
<access>local</access>
<affected>
<package name="media-sound/pulseaudio" auto="yes" arch="*">
<unaffected range="ge">0.9.9-r54</unaffected>
<vulnerable range="lt">0.9.9-r54</vulnerable>
</package>
</affected>
<background>
<p>
PulseAudio is a network-enabled sound server with an advanced plug-in
system.
</p>
</background>
<description>
<p>
Tavis Ormandy and Julien Tinnes of the Google Security Team discovered
that the pulseaudio binary is installed setuid root, and does not drop
privileges before re-executing itself. The vulnerability has
independently been reported to oCERT by Yorick Koster.
</p>
</description>
<impact type="high">
<p>
A local user who has write access to any directory on the file system
containing /usr/bin can exploit this vulnerability using a race
condition to execute arbitrary code with root privileges.
</p>
</impact>
<workaround>
<p>
Ensure that the file system holding /usr/bin does not contain
directories that are writable for unprivileged users.
</p>
</workaround>
<resolution>
<p>
All PulseAudio users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/pulseaudio-0.9.9-r54"</code>
</resolution>
