Unknown vulnerability in an ISAPI plugin for ISS Server Sensor 7.0 XPU 20.16, 20.18, and possibly other versions before 20.19, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code in Internet Information Server (IIS) via a certain URL through SSL.
The default configuration of BlackICE Agent 3.1.eal and 3.1.ebh has a high tcp.maxconnections setting, which could allow remote attackers to cause a denial of service (memory consumption) via a large number of connections to the BlackICE system that consumes more resources than intended by the user.
ISS RealSecure 3.2.1 and 3.2.2 allows remote attackers to cause a denial of service via a flood of fragmented packets with the SYN flag set.
Memory leak in RealSecure Event Collector 6.5 allows attackers to cause a denial of service (memory consumption and crash).
