The SMTP ALG in Clavister CorePlus before 8.80.04, and 8.81.00, does not properly parse SMTP commands in certain circumstances, which allows remote attackers to bypass address blacklists.

The AntiVirus engine in the HTTP-ALG in Clavister CorePlus before 8.81.00 and 8.80.03 might allow remote attackers to bypass scanning via small files.

The IKE implementation in Clavister CorePlus before 8.80.03, and 8.80.00, does not properly validate certificates during IKE negotiation, which allows remote attackers to cause a denial of service (gateway stop) via certain certificates.

The Internet Key Exchange version 1 (IKEv1) implementation in Clavister Client Web allows remote attackers to cause a denial of service and possibly execute arbitrary code via 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.
