An integer underflow flaw, leading to a buffer over-read, was found in the way OpenSSL handled TLS 1.1, TLS 1.2, and DTLS (Datagram Transport Layer Security) application data record lengths when using a block cipher in CBC (cipher-block chaining) mode. A malicious TLS 1.1, TLS 1.2, or DTLS client or server could use this flaw to crash its connection peer.
