ISS Internet Security Systems BlackICE Defender

Buffer overflow in ISS BlackICE Defender 2.9 and earlier, BlackICE Agent 3.0 and 3.1, and RealSecure Server Sensor 6.0.1 and 6.5 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a flood of large ICMP ping packets.

BlackIce Defender 2.1 and earlier, and BlackIce Pro 2.0.23 and earlier, do not properly block Back Orifice traffic when the security setting is Nervous or lower.
