+  <description>
+    <p>
+    Daniel B. Cid discovered that DenyHosts used an incomplete regular
+    expression to parse failed login attempts, a different issue than GLSA
+    200701-01.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A remote unauthenticated attacker can add arbitrary hosts into the
+    blacklist, including the "all" keyword, by submitting specially crafted
+    version identification strings to the SSH server banner. An attacker
+    may use this to prevent legitimate users from accessing a host
+    remotely.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All DenyHosts users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-admin/denyhosts-2.6-r1&quot;</code>
