Out of band release from Microsoft coming next Tuesday for Visual Studio with extra protection of the source issue in IE. They will be patching a few critical extra holes in IE at the same time. No details yet as to what issues are going to be patched. Most likely they will be significant and possibly already being exploited since Microsoft has not been deviating much for their patch Tuesday schedule recently. They hint that customers that are already up to date with security updates are not vulnerable to known attack so this could be more about fixing the source of a known issue to prevent exploitation from other attack vectors. The bulletin points out that developers will have to keep an eye out for any applications that use this vulnerable functionality and take action to mitigate this risk.
