+	  <p>A workspace buffer overflow vulnerability was found in the .upper()
+	  and .lower() string type methods of VCL.</p>
+	  <p>This can be used as a remote denial of service (DoS) vector to make
+	  the child process segfault or assert, and then restart.</p>
+	  <p>Effectively exploiting this vulnerability requires prior knowledge
+	  about the VCL in use and the ability to craft a request that contains a
+	  string that is long enough to fill the remaining workspace at the call
+	  site while staying under the different request size limits
+	  (http_req_size, http_req_hdr_len, ..etc).</p>
