Windows Update 2019-08 Cumulative Update has broken VBA code use case

Anonymous

An issue with VBA code has started to be seen by some of my users and also by me this morning. I have tracked it down to have been caused by the latest 2019-08 Cumulative Update (e.g. KB4511553) and it is affecting all combinations of Windows and Office that I have seen so far- from Windows Server 2008 to Windows 10 & Office 2003(!) to Office 2016. 

The test code below demonstrates the problem. The method "Test" executes with no errors before the 2019-08 cumulative update is installed (or after it is uninstalled). However, after the update, the scenario of passing an empty ParamArray parameter to another method as a Variant parameter causes an error to be thrown on the declaration line of the second method. (Error 5: Invalid procedure call or argument).

Sub Test()

    Test1 "A", "B"   'Works OK with and without Windows Update

    Test1            'Fails after Windows Update

End Sub

Sub Test1(ParamArray P() As Variant)

    Test2 P

End Sub

Sub Test2(ByVal P As Variant)    'Error occurs on this line

End Sub

This is causing errors in my Microsoft Access application, but I have also tried this code in Word 2016 and the same issue occurs there too.

Can somebody validate this, please? I'm not really sure what the correct way of reporting this problem is.

Thanks

Chris

    Hi Scot,

    Thank you for the update.

    As per your suggestion, I am working around the issue by passing "Empty" instead of the empty ParamArray and detecting that within the inner function.

    For future reference, where am I actually supposed to go to report stuff like this to Microsoft? I couldn't find a way to report a problem with a specific Windows Update. I asked @MicrosoftHelps on Twitter and they directed me to UserVoice - which didn't seem right as it appears as more of an idea submission hub. So I found this forum and posted here.

    Thanks

    Chris

    I am a Sr. Escalation Engineer for Microsoft, and we are already working multiple support cases that have been opened for this issue.  The update that was released yesterday contained a change in the oleaut32.dll that mitigates a specific security exploit.

    Scot

    I forgot to ask, what is the KB number for that update?

    While I'm not directly connected to any of the teams that can respond to your suggestions and requests, I'm at least inside "the moat", so I 'll do what I can to find the people who can actually do something there.  So that we don't spam this forum thread about issues not directly related to the original post, please contact me at my Microsoft "dot com" address.

    I hope that those who read this reply will do me the respect of not abusing that.
