119: An incorrectly formatted ClientHello handshake message could cause
120: OpenSSL to parse past the end of the message. An attacker could use this flaw
121: to trigger an invalid memory access, causing a crash of an application linked
122: to OpenSSL. As well, certain applications may expose the contents of parsed

124: <p>
125: Applications are only affected if they act as a server and call
126: SSL_CTX_set_tlsext_status_cb on the server's SSL_CTX. It is believed
127: that nothing in the base OS uses this. Apache httpd started using this
128: in v2.3.3; this is newer than the version in ports.
