+  <background>
+    <p>sudo allows a system administrator to give users the ability to run
+      commands as other users. Access to commands may also be granted on a
+      range to hosts.
+    </p>
+  </background>
+  <description>
+    <p>Multiple vulnerabilities have been found in sudo:</p>
+    
+    <ul>
+      <li>sudo does not correctly validate the controlling terminal on a system
+        without /proc or when the tty_tickets option is enabled.
+      </li>
+      <li>sudo does not properly handle the clock when it is set to the epoch.</li>
+    </ul>
+  </description>
+  <impact type="high">
+    <p>A local attacker with sudo privileges could connect to the stdin,
+      stdout, and stderr of the terminal of a user who has authenticated with
+      sudo, allowing the attacker to hijack the authorization of the other
+      user. Additionally, a local or physically proximate attacker could set
+      the system clock to the epoch, bypassing time restrictions on sudo
+      authentication.
+    </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-1.8.6_p7"
