[New-bugs-announce] [issue39570] Python 3.7.3 Crash on msilib actions

[UltraLutra]

New submission from UltraLutra <eitaniasaf at gmail.com>:

Hello,

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')
query.Execute(None)
for i in range(6):
    record = query.Fetch()
record.GetString(5)

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