|漏洞详情
Windows95/98是Microsoft公司开发的流行的通用操作系统。Windows95/98在处理winpopup消息时存在漏洞,远程攻击者可能利用此漏洞对机器进行拒绝服务攻击。当Windows95/98收到一个畸型的winpopup消息时,Windows95/98发生不可预料的错误:系统崩溃、蓝屏、重起动、死锁或者丢失网络连接等等。执行nbtstat-A,如果看到VICTIM<03>UNIQUERegistered并且可以telnet139的话,就可能受此漏洞影响。

Unpredictable results, including system crashes, lock-ups, reboots, and loss of network connectivity, can occur in Windows 95/98 if a NetBIOS session packet is received with the source host name set to NULL.

/* 	- el8.org advisory: RFParalyze.c 

	code by rain forest puppy <[email protected]>   -
   	coolness exhibited by Evan Brewer <[email protected]> -

	- Usage: RFParalyze <IP address> <NetBIOS name>

	where <IP address> is the IP address (duh) of the target (note:
	not DNS name).  <NetBIOS name> is the NetBIOS name (again, duh) of
	the server at the IP address given.  A kiddie worth his scripts
	should be able to figure out how to lookup the NetBIOS name.  
	Note: NetBIOS name must be in upper case.

	This code was made from a reverse-engineer of 'whisper', a 
	binary-only exploit found in the wild.

	I have only tested this code on Linux.  Hey, at least it's
	not in perl... ;)   -rfp
