The term WinNuke refers to a remote denial-of-service attack (DoS) that affected the Microsoft Windows 95, Microsoft Windows NT and Microsoft Windows 3.1x computer operating systems. The exploit sent a string of OOB (out of band) data to the target computer on TCP port 139 (NetBIOS), causing it to lock up and display a Blue Screen of Death. This doesn't damage or change the data on the computer's hard disk, but any unsaved data would be lost.
The so-called OOB simply means that the malicious TCP packet contained an Urgent Pointer (URG). The Urgent Pointer is a rarely used field in the TCP header, used to indicate that some of the data in the TCP stream should be processed quickly by the recipient. Affected operating systems didn't handle the Urgent Pointer field correctly.
