File and Printer Sharing Insecure in XP SP2

ProKras writes "German magazine PC-Welt has discovered a major security flaw in Windows XP SP2 when installing over SP1. The article says that 'with a certain configuration, your file and printer sharing data are visible worldwide, despite an activated Firewall.' The magazine claims they were 'able to discover private documents on easily accessible computers on the Internet' and that the configuration is fairly common."
