[ MDVSA-2009:120 ] openssl

[dude67]

_______________________________________________________________________

Package : openssl
Date : May 21, 2009
Affected: 2008.1, 2009.0, 2009.1
_______________________________________________________________________

Problem Description:

Multiple security vulnerabilities has been identified and fixed
in OpenSSL:

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-2009-1377)

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-2009-1378)

The updated packages have been patched to prevent this.
