" New Teardrop-like TCP/IP Denial of Service Program
Market Bulletin, January 1997

Microsoft has been alerted to a new TCP/IP denial of service attack that can be used by someone with malicious intent to crash Microsoft® Windows 95 and Windows NT® machines. Microsoft is working aggressively to develop a fix for both operating systems, which has been referred to by a couple of different names including "newtear" and "bonk". As soon fixes are available, this bulletin will be updated to include information on how to obtain these fixes.

Description of the Issue
This "newtear" issue is caused by a problem with the way the Microsoft TCP/IP stack handles certain exceptions caused by mis-formed UDP header information. This situation does not occur in properly formed TCP/IP packets and must be generated by a program with malicious intent.

When Windows NT or Windows 95 receives one of these mis-formed UDP packets, it will cause either operating system to crash. However, it does not in any way compromise the privacy of user data. It is unclear if there are any other environments that might also be affected by this issue. "
