120: An incorrectly formatted ClientHello handshake message could cause
121: OpenSSL to parse past the end of the message. An attacker could use this flaw
122: to trigger an invalid memory access, causing a crash of an application linked

126: Applications are only affected if they act as a server and call
127: SSL_CTX_set_tlsext_status_cb on the server's SSL_CTX. It is believed
128: that nothing in the base OS uses this. Apache httpd started using this
