Windows 7 SMB Kernel Crash Video

Back on November 11th, 2009 we confirmed Laurent Gaffié’s remote exploit for Windows that causes a kernel crash. The operating system actually freezes creating a denial of service when for example a user is tricked into clicking on a link to a malicious SMB share on a web page. The SMB client goes into an infinite loop when processing this malformed request according to Microsoft. The video below demonstrates this effect, having a user click a web site link and showing the crash.
