Microsoft ships one-click 'workaround' for critical SMB2 flaw

Posted by Ryan Naraine @ 1:56 pm

With exploit code in circulation and facing a race against time to fix the SMB v2 vulnerability haunting Windows Vista and Windows Server 2008, Microsoft today shipped a one-click “fix-it” workaround to help users avoid malicious hacker attacks.

The fix-it package, which was added to Redmond’s pre-patch advisory, effectively disables SMBv2 and then stops and starts the Server service. It provides temporary mitigation from remote code execution attacks targeting the known — and still unpatched — vulnerability.
Microsoft cautioned that disabling SMBv2 may slow down SMB connections between Windows Vista and Windows Server 2008 machines.
