Description:
Thomas Walpuski has reported a vulnerability in KAME Racoon, which can be exploited by malicious people to cause a DoS (Denial of Service) on users' connections.
The vulnerability is caused due to errors in the authentication of delete messages and in the handling of "INITIAL-CONTACT" notifications. These make it possible to perform unauthorised deletion of IPsec and ISAKMP Security Associations (SAs), which are used to describe how communicating entities should use security services.
All versions of Racoon are reportedly affected.
Solution:
This has reportedly been fixed in revision 1.83 of "isakmp_inf.c" available in the CVS repository.
