    sudo allows a system administrator to give users the ability to run
    commands as other users.

  <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 "&gt;=app-admin/sudo-1.7.4_p3-r1"</code>
  </resolution>
