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

127: Applications are only affected if they act as a server and call

129: that nothing in the base OS uses this. Apache httpd started using this
