## Description

Multiple memory leaks in the dtls1\_process\_out\_of\_seq\_message function in
ssl/d1\_both.c in OpenSSL 0.9.8k and earlier 0.9.8 versions allow remote
attackers to cause a denial of service (memory consumption) via DTLS
records that (1) are duplicates or (2) have sequence numbers much greater
than current sequence numbers, aka "DTLS fragment handling memory leak."
