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.
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.
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.
Check Point VPN-1/FireWall-1 4.1 base.def contains a default macro, acceptfw1rdp, which can allow remote attackers to bypass intended restrictions with forged RDP (internal protocol) headers to UDP port 259 of arbitrary hosts.
Check Point VPN-1/FireWall-1 4.1 SP2 with Fastmode enabled allows remote attackers to bypass access restrictions via malformed, fragmented packets.
Check Point FireWall-1 SecuRemote/SecuClient 4.0 and 4.1 allows clients to bypass the "authentication timeout" by modifying the toexpire or expire values in the client's users.C configuration file.
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.
The default configuration of SecuRemote for Check Point Firewall-1 allows remote attackers to obtain sensitive configuration information for the protected network without authentication.
FireWall-1 4.1 with a limited-IP license allows remote attackers to cause a denial of service by sending a large number of spoofed IP packets with various source addresses to the inside interface, which floods the console with warning messages and consumes CPU resources.
