Hi,
the following CVE (Common Vulnerabilities & Exposures) ids were
published for openssl.

CVE-2009-1377[0]:
| 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[1]:
| 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."

CVE-2009-1379[2]:
| Use-after-free vulnerability in the dtls1_retrieve_buffered_fragment
| function in ssl/d1_both.c in OpenSSL 1.0.0 Beta 2 allows remote
| attackers to cause a denial of service (openssl s_client crash) and
| possibly have unspecified other impact via a DTLS packet, as
| demonstrated by a packet from a server that uses a crafted server
| certificate.

If you fix the vulnerabilities please also make sure to include the
CVE ids in your changelog entry.
