Check Point Firewall-1 4.1 up to NG AI R55 allows remote attackers to obtain potentially sensitive information by sending an Internet Key Exchange (IKE) with a certain Vendor ID payload that causes Firewall-1 to return a response containing version and other information.

The Internet Key Exchange version 1 (IKEv1) implementation in Check Point products allows remote attackers to cause a denial of service via certain crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to.

Directory traversal vulnerability in Check Point Firewall-1 R55W before HFA03 allows remote attackers to read arbitrary files via an encoded .. (dot dot) in the URL on TCP port 18264.

Buffer overflow in the ISAKMP functionality for Check Point VPN-1 and FireWall-1 NG products, before VPN-1/FireWall-1 R55 HFA-03, R54 HFA-410 and NG FP3 HFA-325, or VPN-1 SecuRemote/SecureClient R56, may allow remote attackers to execute arbitrary code during VPN tunnel negotiation.
