A vulnerability classified as critical has been found in Check Point VPN-1 and SecureClient up to 1.4.1 SP5 (Network Encryption Software). Affected is an unknown function of the component ISAKMP Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Stack-based buffer overflow in Check Point VPN-1 Server 4.1 through 4.1 SP6 and Check Point SecuRemote/SecureClient 4.1 through 4.1 build 4200 allows remote attackers to execute arbitrary code via an ISAKMP packet with a large Certificate Request packet.

The bug was discovered 02/02/2004. The weakness was shared 02/04/2004 by Chris Wysopal with ISS X-Force (Website). The advisory is shared for download at xforce.iss.net. This vulnerability is traded as CVE-2004-0040. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 2 days. During that time the estimated underground price was around $5k-$25k.

Upgrading to version 4.1 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at securityfocus.com. The best possible mitigation is suggested to be upgrading to the latest version. Attack attempts may be identified with Snort ID 2378. In this case the pattern |07| is used for detection.
