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