CVE-2009-1377
The dtls1_buffer_record function in ssl/d1_pkt.c in OpenSSL 0.9.8k and
earlier 0.9.8 versions allows remote attackers to cause a denial of
service (memory consumption) via a large series of 'future epoch' DTLS
records that are buffered in a queue, aka 'DTLS record buffer
limitation bug.'

CVE-2009-1378
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.'");
