A new security advisory from Microsoft shines the light on a denial-of-service bug in Windows 7 and Server 2008 that could be hit to crash the system but not cause other harm.
The flaw in the Server Message Block (SMB) protocol only affects Windows 7 and Server 2008, and is unrelated to the previously fixed MS09-050 flaw affecting SMBv2, according to the Internet Storm Center. Microsoft says it does not yet know of any attacks against the flaw, but it has seen "public, detailed exploit code that would cause a system to stop functioning or become unreliable." A patch is not yet availabe.
