Checkpoint » Firewall-1 : Security Vulnerabilities, CVEs, (Overflow)

Heap-based buffer overflow in ASN.1 decoding library in Check Point VPN-1 products, when Aggressive Mode IKE is implemented, allows remote attackers to execute arbitrary code by initiating an IKE negotiation and then sending an IKE packet with malformed ASN.1 data.

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.

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.

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.

Buffer overflow in Getkey in the protocol checker in the inter-module communication mechanism in Check Point VPN-1/FireWall-1 4.1 and earlier allows remote attackers to cause a denial of service.
