(IBM Issues Fix) OpenSSL DTLS Processing Bugs Let Users Deny Service
SecurityTracker Alert ID:  1022481
SecurityTracker URL:  http://securitytracker.com/id/1022481
CVE Reference:   CVE-2009-1377, CVE-2009-1378, CVE-2009-1379   (Links to External Site)
Updated:  Jul 22 2009
Original Entry Date:  Jun 30 2009
Impact:   Denial of service via local system, Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Several vulnerabilities were reported in OpenSSL. A user can cause denial of service conditions.

A user can send specially crafted DTLS records with a future epoch to consume excessive memory on the target system.

A user can send specially crafted DTLS messages to trigger a memory leak and consume excessive memory on the target system.

A user can send DTLS data with a specially crafted certificate to cause freed memory to be used by the dtls1_retrieve_buffered_fragment() function in 'ssl/d1_both.c'. OpenSSL 1.0.0 Beta 2 is affected.

Daniel Mentz reported the above listed vulnerabilities.

A remote user can send a DTLS ChangeCipherSpec packet prior to a ClientHello packet to trigger a null pointer dereference in 'ssl/s3_pkt.c' and cause the target daemon to crash.

A remote user can send an out-of-sequence DTLS handshake message to trigger a null pointer dereference in the dtls1_retrieve_buffered_fragment() function in 'ssl/d1_both.c' and cause the target daemon to crash.

Impact:   A user can consume excessive memory on the target system.

A user can cause an affected application to crash.

Solution:   IBM has issued a fix for IBM AIX for CVE-2009-1377, CVE-2009-1378, and CVE-2009-1379, available at:
