Microsoft acknowledges Windows 7 security threat

Posted: November 15, 2009 in Tech

Researcher Laurent Gaffie discovered a zero-day vulnerability in Windows 7 which basically crashes a Windows 7 system when exploited. The issue is in the SMB (Server Message Block) protocol that forms the backbone of Windows file sharing. When triggered, the flaw results in an infinite loop which renders the computer useless.

The vulnerability actually impacts both Windows 7 and Windows Server 2008 R2.

Microsoft said that they are aware of the exploit code can cause a system to stop functioning; and added that it will “continue to encourage responsible disclosure of vulnerabilities.”
