Description:
Mark Dowd and Neel Mehta of ISS X-Force has discovered a vulnerability in Check Point VPN-1 Server and VPN clients, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the ISAKMP processing during authentication. This can be exploited to cause a buffer overflow by sending packets with an extremely large "Certificate Request" payload, which may allow execution of arbitrary code with SYSTEM or root privileges.

The following products are reportedly affected:
* Check Point VPN-1 Server 4.1 up to and including SP6 with OpenSSL Hotfix
* Check Point SecuRemote/SecureClient 4.1 up to and including build 4200
