Name of the Vulnerable Software and Affected Versions ISS RealSecure Network Sensor versions 5.x through 6.5

Description The issue allows remote attackers to cause a denial of service, resulting in a crash, by sending malformed DHCP packets. This occurs because the packets cause the software to dereference a null pointer.

Recommendations For ISS RealSecure Network Sensor versions 5.x through 6.5, consider restricting access to the network to minimize the risk of exploitation until a patch is available. As a temporary workaround, disabling the handling of DHCP packets may prevent the denial of service.
