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.
Multiple format string vulnerabilities in HTTP Application Intelligence (AI) component in Check Point Firewall-1 NG-AI R55 and R54, and Check Point Firewall-1 HTTP Security Server included with NG FP1, FP2, and FP3 allows remote attackers to execute arbitrary code via HTTP requests that cause format string specifiers to be used in an error message, as demonstrated using the scheme of a URI.
The Log Viewer function in the Check Point FireWall-1 GUI for Solaris 3.0b through 4.1 SP2 does not check for the existence of '.log' files when saving files, which allows (1) remote authenticated users to overwrite arbitrary files ending in '.log', or (2) local users to overwrite arbitrary files via a symlink attack.
Check Point FireWall-1 3.0b through 4.1 for Solaris allows local users to overwrite arbitrary files via a symlink attack on temporary policy files that end in a .cpp extension, which are set world-writable.
The client authentication interface for Check Point Firewall-1 4.0 and earlier generates different error messages for invalid usernames versus invalid passwords, which allows remote attackers to identify valid usernames on the firewall.
Check Point Firewall-1 session agent 3.0 through 4.1 generates different error messages for invalid user names versus invalid passwords, which allows remote attackers to determine valid usernames and guess a password via a brute force attack.
Check Point VPN-1/FireWall-1 4.1 and earlier allows remote attackers to bypass the directionality check via fragmented TCP connection requests or reopening closed TCP connection requests, aka "One-way Connection Enforcement Bypass."
Check Point VPN-1/FireWall-1 4.1 and earlier improperly retransmits encapsulated FWS packets, even if they do not come from a valid FWZ client, aka "Retransmission of Encapsulated Packets."
The inter-module authentication mechanism (fwa1) in Check Point VPN-1/FireWall-1 4.1 and earlier may allow remote attackers to conduct a denial of service, aka "Inter-module Communications Bypass."
