<background>
<p>PolicyKit is a toolkit for controlling privileges for system-wide
services.
</p>
</background>
<description>
<p>Multiple vulnerabilities have been found in PolicyKit:</p>
<ul>
<li>Error messages in the pkexec utility disclose the existence of local
files (CVE-2010-0750).
</li>
<li>The pkexec utility initially checks the effective user ID of its
parent process for authorization, instead of checking the real user ID
(CVE-2011-1485).
</li>
<li>Members of the "wheel" group are able to execute commands as an
administrator without a password (CVE-2011-4945).
</li>
</ul>
</description>
<impact type="high">
<p>A local attacker could gain elevated privileges or sensitive
information.
</p>
</impact>
<workaround>
<p>There is no known workaround at this time.</p>
</workaround>
<resolution>
<p>All PolicyKit users should upgrade to the latest version:</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=sys-auth/polkit-0.104-r1"
</code>
