Siemens SCALANCE and RUGGEDCOM Incorrect Calculation (CVE-2025-4435)

When using a TarFile.errorlevel = 0and extracting with a filter the documented behavior is that any filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0in affected versions is that the member would still be extracted and not skipped. This plug...
