OpenSSL: DTLS fragment handling memory DoS

Published May 19, 2009

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."

Affected products

Remediation

Red Hat statement

This issue did not affect versions of openssl as shipped in Red Hat Enterprise Linux 3 and 4. Note that both the DTLS specification and OpenSSLs implementation is still in development and unlikely to be used in production environments. There is no component shipped in Red Hat Enterprise Linux 5 using OpenSSLs DTLS implementation, except for OpenSSLs testing command line client - openssl.
