Mandriva Linux Security Advisory : openssl (MDVSA-2009:120)
Medium Nessus Plugin ID 38864
SynopsisThe remote Mandriva Linux host is missing one or more security updates.
DescriptionMultiple 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.
SolutionUpdate the affected packages.
