The bulletin with patches for Microsoft Office and Visual Studio also carries a "critical" rating, while patches for Microsoft SharePoint Services will be released with "moderate" severity ratings.
The company also plans to issue an "important" fix for bugs in its .NET Framework.
It is not yet known whether a promised update
