+  <background>
+    <p>libssh is a multiplatform C library implementing the SSHv2 protocol on
+      client and server side.

+  <description>
+    <p>It was discovered that libssh could crash when AES-CTR ciphers are used.</p>
+  </description>
+  <impact type="low">
+    <p>A remote attacker running a malicious client or server could possibly
+      crash the counterpart implemented with libssh and cause a Denial of
+      Service condition.
+    </p>
+  </impact>
+  <workaround>
+    <p>Disable AES-CTR ciphers. If you implement a server using libssh it is
+      recommended to use a prefork model so each session runs in an own
+      process.
+    </p>
+  </workaround>
+  <resolution>
+    <p>All libssh users should upgrade to the latest version:</p>
+    
+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=net-libs/libssh-0.9.4"
+    </code>
