ISS RealSecure Network Sensor 5.x through 6.5 allows remote attackers to cause a denial of service (crash) via malformed DHCP packets that cause RealSecure to dereference a null pointer.

ISS RealSecure Network Sensor 5.x through 6.5 allows remote attackers to cause a denial of service (crash) via malformed DHCP packets that cause RealSecure to dereference a null pointer. ISS RealSecure Network Sensor "informational signatures" fail to properly process certain types of DHCP traffic, thereby causing the sensor to crash. RealSecure is the commercial Intrusion Detection System (IDS) distributed and maintained by ISS. RealSecure becomes unstable when processing some of the DHCP signatures packaged with the system. Due to the construction of the three DHCP signatures (DHCP_ACK - 7131, DHCP_Discover - 7132, and DHCP_Request - 7133), the RealSecure software may become unstable and crash. This is due to the software attempting to dereference a null pointer. If the sensor is disabled, further attacks may go unnoticed. Vulnerabilities exist in ISS RealSecure Network Sensor versions 5.x to 6.5
