Symantec Norton Personal Firewall 2002 allows remote attackers to bypass the portscan protection by using a (1) SYN/FIN, (2) SYN/FIN/URG, (3) SYN/FIN/PUSH, or (4) SYN/FIN/URG/PUSH scan. Symantec Norton Personal Firewall 2002 (NPW)is a firewall solution for home and small office machines based on some versions of the Microsoft Windows operating systems. It has a variety of features, including the ability to detect and dynamically block portscans. An issue has been reported with the manner in which Personal Firewall 2002 handles portscans. Reportedly, only SYN scans are detected. An attacker may scan with a variety of other methods, including SYN/FIN packets and evade the protective features of NPW. This issue may affect Norton Internet Security 2002, however this has not been confirmed
