TITLE:
Check Point VPN-1 ISAKMP Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA10795

VERIFY ADVISORY:
http://www.secunia.com/advisories/10795/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
Check Point VPN-1 SecureClient
Check Point VPN-1 SecuRemote
Check Point VPN-1 Server 4.x

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

SOLUTION:
Check Point no longer supports the affected versions and
therefore advises customers to upgrade to the NG versions
of the products.

PROVIDED AND/OR DISCOVERED BY:
Mark Dowd and Neel Mehta, ISS X-Force.
