Security research organization found that the Windows 7 in the presence of a new vulnerability in the implementation of the system will be SMB2 protocol attacks cause a system crash or restart.Since 1999, this is a rarely encountered since the loopholes, if deliberately send a wrong request network protocol system Windows 7 page fault occurs and causes "blue screen of death."
Researchers discovered the vulnerability, said Laurent Gaffie it affects 32-bit and 64-bit Vista and Windows Server 2008 and Windows 7, the vulnerability stems from Windows Vista, because these systems have adopted SMB 2.0.Windows 2000 and XP are not affected by this vulnerability, because they do not use SMB 2.0.Security research institutions are testing the code on this issue, but in the test version of Windows 7 RTM is not affected by this so-called vulnerability.
It is reported that security researchers have reported the flaw to Microsoft, but Microsoft has not issued an official statement on this patch, let alone released.Before access to security fixes, security experts recommend users to use the new system is temporarily closed SMB (Server Message Block) function.
