I'm trying to read MSI files using msilib.
Some files make python crash on Record.GetString of a specific cell.
Attached is one of the files that causes the crash, and this is the code that is causing it to crash:
db = msilib.OpenDatabase('6bcd682374529631be60819d20a71d9d40c67bf0b1909faa459298eda998f833', msilib.MSIDBOPEN_READONLY)
query = db.OpenView(f'SELECT * FROM Registry')
for i in range(6):
    record = query.Fetch()

The crash seems to be by trying to read the Value columns of the last row in the Registry table.

I personally don't feel like downloading a binary from b.p.o and opening it on my machine.

Can you provide more information about the issue? For instance, what do you mean by crash? Do you have any stack trace or other output?

What is the value in the registry table that it is trying to read and failing?

Yep, this is malware. Don't download the file.

If this is a CPython issue that you want fixed, please provide a script to generate the MSI.
