Workflow Manager - impacted by Microsoft IE scripting engine memory corruption?

[Ralph_Crowley]

Have anyone else who uses WFM applied the Microsoft patch for the IE scripting engine memory corruption vulnerability & noticed any impacts? In our environment we can no longer access any of our WFM instances (production or dev) since applying a fix for this JScript vulernablity. We've opened a support case, but curious if others have noticed any issues. Thanks

Confirmed if changing permissions on the jscript.dll as advised by Microsoft will break WFM.:

Hello Ralph,
Have you tried accessing Workflow Manager in any other browsers in your environment? The product's UI was updated a few releases ago and supports any major browser including Chrome and Firefox.

Yes, the change actually blocks all browser access to WFM (chrome, edge, etc), along with IE.  The change updates permissions on the Jscript.dll file to deny access to everyone, & apparently this is not just IE specific.
