Who is Vulnerable?
Vulnerability Description Norton Internet Security is a security solution produced by Symantec corporation. If the Firewall component allows traffic on port 137/UDP, this traffic will be parsed as NetBIOS Name Service messages. There exists a vulnerability in the Symantec Firewall product line. A specially crafted NetBIOS Name Service Response message can cause a stack buffer overflow. This can allow the attacker to run arbitrary code with kernel privileges. In a simple attack case, the vulnerable system will terminate abnormally (blue screen) with the error message "DRIVER_IRQL_NOT_LESS_OR_EQUAL" in symdns.sys. In a more sophisticated attack, where the traffic is properly crafted, it is possible for the remote attacker to write arbitrary data on the stack and control the process flow, which leads to the execution of arbitrary code on the remote client, running with kernel privileges.
