一行C代码，干掉 win2K/XP

for( ; ; )printf("hung up\t\t\b\b\b\b\b\b");



于是， 整个世界清静了......



=====================

我怀疑是 \b 造成 对缓冲大小判断的失误，
谁有空去跟一跟，告诉我到底怎么回事。

Microsoft Windows NT CSRSS Memory Access Violation Vulnerability

CSRSS.EXE is the Windows NT Client Server Run-time Subsystem. It is responsible for console windows and the creation and deletion of threads. The Windows NT kernel is dependant on this service and will halt if the service stops for any reason.

If certain combinations of special "whitespace" characters followed by "backspace" characters are output in high-level console I/O, a user could successfully crash a Windows NT, 2000, or XP system.
