Check Point Firewall-1 3.0b through 4.0 SP1 follows symlinks and creates a world-writable temporary .cpp file when compiling Policy rules, which could allow local users to gain privileges or modify the firewall policy.

Check Point VPN-1 4.1SP4 using SecuRemote returns different error messages for valid and invalid users, with prompts that vary depending on the authentication method being used, which makes it easier for remote attackers to conduct brute force attacks.

Nokia Firewall Appliances running IPSO 3.3 and VPN-1/FireWall-1 4.1 Service Pack 3, IPSO 3.4 and VPN-1/FireWall-1 4.1 Service Pack 4, and IPSO 3.4 or IPSO 3.4.1 and VPN-1/FireWall-1 4.1 Service Pack 5, when SYN Defender is configured in Active Gateway mode, does not properly rewrite the third packet of a TCP three-way handshake to use the NAT IP address, which allows remote attackers to gain sensitive information.

Buffer overflow in the GUI authentication code of Check Point VPN-1/FireWall-1 Management Server 4.0 and 4.1 allows remote attackers to execute arbitrary code via a long user name.

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.

Check Point FireWall-1 allows remote attackers to cause a denial of service (high CPU) via a flood of packets to port 264.

ZoneAlarm and ZoneAlarm Pro allows a local attacker to cause a denial of service by running a trojan to initialize a ZoneAlarm mutex object which prevents ZoneAlarm from starting.

The default configuration of SecuRemote for Check Point Firewall-1 allows remote attackers to obtain sensitive configuration information for the protected network without authentication.

Format string vulnerability in Check Point VPN-1/FireWall-1 4.1 allows a remote authenticated firewall administrator to execute arbitrary code via format strings in the control connection.
