Description

This module performs a Denial of Service Attack against Datagram TLS in
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h.
This occurs when a DTLS ClientHello message has multiple fragments and the
fragment lengths of later fragments are larger than that of the first, a
buffer overflow occurs, causing a DoS.
