Description Mark J. Cox 2009-05-18 08:52:38 UTC
Common Vulnerabilities and Exposures assigned an identifier CVE-2009-1377 to the following vulnerability:

Records are buffered if they arrive with a future epoch to be
processed after finishing the corresponding handshake. There is
currently no limitation to this buffer allowing an attacker to perform
a DOS attack with sending records with future epochs until there is no
memory left. This patch adds the pqueue_size() function to detemine
the size of a buffer and limits the record buffer to 100 entries.

Comment 2 Jan Lieskovsky 2009-05-19 19:45:39 UTC
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."

Comment 7 Tomas Hoger 2009-06-02 09:25:14 UTC
This issue did not affect versions of openssl as shipped in Red Hat Enterprise Linux 3 and 4.

This issue affects openssl version as shipped in Red Hat Enterprise Linux 5 and it will be addressed in the openssl packages update in Red Hat Enterprise Linux 5.4.  There is no update planned before than, as both DTLS specification and OpenSSL's 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 OpenSSL's DTLS implementation, except for OpenSSL's testing command line client - openssl.
