A security researcher of Insecure.org found an exploit in Windows 7 that can be abused to crash systems on a LAN (Local Area Network). The security flaw has been found in the SMB protocol that is responsible for shared access to printers, files, etc. He suggest to turn off file/printer sharing and close all SMB ports.
Experts state that there will probably a couple other security flaws that haven’t been revealed yet. Microsoft is hard at work to release an update that will fix the security flaws.
Disable File/Printer Sharing
Laurence Gaffié, who found the bug in Windows 7, suggests to completely disable the SMB feature and close the ports.
Luckily, the security flaw doesn’t allow hackers to gain access to your system. The biggest threat would be a DOS attack on your PC. Theoretically, many Windows-based servers are at risk, because Windows Server 2008 RC2 can also be exploited that way.
