MS09-050 addresses the much talked about SMB2 Negotiation vulnerability. A crafted SMB packet could crash the Windows Vista/2008 systems with blue screen.
The OpenVAS plugin for checking MS09-050 hotfix is now available in the svn. This doesn’t require any credentials. The patched system responds differently to a particular SMB negotiation request (a crafted PID’s low_id field) from an un-patched system. The response is verified to confirm if the patch is installed. This has been tested on Windows Vista and 2008.
