To the thread: This may be usefull info or may not be worth the trouble. I'll leave that up to the gurus on this thread to answer. From Langa List Newsletter Alert! Almost All Copies Of Windows Have This Bug! Microsoft has just released info and a patch on something called the "Fragmented IGMP Packet Vulnerability." Normalspeak: A malicious or incompetent person could potentially cause your PC to slow to a crawl or even crash by sending you a pile of a special kind of normally- invisible internet information packets. Geekspeak (feel free to skip this paragraph): IGMP stands for Internet Group Management Protocol; it's a protocol originally and mainly designed for hosts on multi-access networks to communicate their group membership information to routers, but has been extended and modified since its inception. It's now used in multicasting where data is sent to an IP address to reach multiple hosts. Normal IGMP packets aren't a problem, but if a Windows machine has to process fragmented packets, trouble can ensue. This affects all versions of Windows, and is a basis for potential denial- of-service attacks. This is brand-new security alert, and the patches are just now becoming available. If you want the patch (and I recommend you get it), Microsoft says they'll soon be posted as follows: Patches: Windows 95: available "shortly" Windows 98: a patch will be available via Windows Update on about Sept 9th, and is available right now for manual download at microsoft.com Windows NT Workstation & Server 4.0;Windows NT Server, Enterprise Edition: ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT40/hotfixes-postSP5/IGMP-fix/ Windows NT Server 4.0, Terminal Server Edition: ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT40TSE/hotfixes-postSP5/IGMP-fix/ More info: microsoft.com TheCow
