+  <title>Heartbeat: Denial of service</title>
+  <synopsis>
+    Heartbeat is vulnerable to a Denial of Service which can be triggered by a
+    remote attacker without authentication.

+  <background>
+    <p>
+    Heartbeat is a component of the High-Availability Linux project. It is
+    used to perform death-of-node detection, communications and cluster
+    management.

+    <p>
+    Yan Rong Ge discovered that the peel_netstring() function in
+    cl_netstring.c does not validate the "length" parameter of user input,
+    which can lead to an out-of-bounds memory access when processing
+    certain Heartbeat messages (CVE-2006-3121). Furthermore an unspecified
+    local DoS issue was fixed (CVE-2006-3815).

+  <impact type="normal">
+    <p>
+    By sending a malicious UDP Heartbeat message, even before
+    authentication, a remote attacker can crash the master control process
+    of the cluster.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Heartbeat users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose sys-cluster/heartbeat</code>
