+  <background>
+    <p>c-ares is a C library for asynchronous DNS requests (including name
+      resolves).
+    </p>
+  </background>
+  <description>
+    <p>A hostname with an escaped trailing dot (such as “hello\.”) would
+      have its size calculated incorrectly leading to a single byte written
+      beyond the end of a buffer on the heap.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>A remote attacker, able to provide a specially crafted hostname to an
+      application using c-ares, could potentially cause a Denial of Service
+      condition.
+    </p>
+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All c-ares users should upgrade to the latest version:</p>
