<description>
<p>
Multiple vulnerabilities have been reported in sudo:
</p>
<ul>
<li>Evan
Broder and Anders Kaseorg of Ksplice, Inc. reported that the sudo
'secure path' feature does not properly handle multiple PATH variables
(CVE-2010-1646).</li>
<li>Markus Wuethrich of Swiss Post reported that
sudo fails to restrict access when using Runas groups and the group
(-g) command line option (CVE-2010-2956).</li>
</ul>
</description>
<impact type="high">
<p>
A local attacker could exploit these vulnerabilities to gain the
ability to run certain commands with the privileges of other users,
including root, depending on the configuration.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All sudo users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-admin/sudo-1.7.4_p3-r1&quot;</code>
</resolution>
