(Apple Issues Fix) KAME Racoon Hash Validation Flaw Lets Remote Users Delete Security Associations
SecurityTracker Alert ID:  1009184
SecurityTracker URL:  http://securitytracker.com/id/1009184
CVE Reference:   CVE-2004-0164   (Links to External Site)
Date:  Feb 24 2004
Impact:   Denial of service via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): isakmp_inf.c file version 1.82 and prior versions
Description:   Some vulnerabilities were reported in the KAME Racoon daemon. A remote user can cause IPSec security associations (SAs) to be deleted.

In January 2004, it was reported that the software fails to validate hash values in certain cases. A remote user can send messages to cause established SAs to be deleted.

It is reported that a remote user can send a delete message that contains the initiator cookie for a main/aggressive/base mode transaction and includes an arbitrary hash value. If the IP source address is correct and the ISAKMP SA has not yet been setup, the target system will incorrectly honor the delete message.

It is also reported that a remote user can send an INITIAL-CONTACT notification to cause all IPSec SAs associated with the destination address to be deleted.

A demonstration exploit scenario is described in the Source Message.

Impact:   A remote user can cause SAs to be deleted.
Solution:   Apple has released a fix as part of Security Update 2004-02-23, available at:
