--
Summary:
This event is generated when an attempt is made to exploit a known
vulnerability in Checkpoint VPN-1.

--
Impact:
Unauthorized administrative access to Checkpoint VPN-1 systems

--
Detailed Information:
Checkpoint VPN-1, SecuRemote and SecureClient contain an error that
affects the processing of large Certificate requests to the VPN service.
By sending a large amount of data in the Certificate Request payload an
attacker may cause a buffer overflow condition to occur, presenting an
opportunity to execute code of their choosing with the privileges of the
user running the service, usually root.

--
Affected Systems:
	CheckPoint Software FW-1 1.4.1 Service packs prior to SP6
	CheckPoint Software FW-1 Next Generation FP1, FP0
	CheckPoint Software VPN-1 1.4.1 SP5a
	CheckPoint Software VPN-1 Next Generation FP1, FP0

--
Attack Scenarios:
An attacker could supply a large Certificate Request payload containing
code to be executed on the system.

--
Ease of Attack:
Proof of concept code exists.

--
False Positives:
None known

--
False Negatives:
None known

--
Corrective Action:
Upgrade to the latest non-affected version of the software

Apply the appropriate vendor supplied patches
