When using a TarFile.errorlevel = 0 and 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 = 0 in affected versions is that the member would still be extracted and not skipped.

Al usar TarFile.errorlevel = 0 y extraer con un filtro, el comportamiento documentado es que cualquier miembro filtrado se omite y no se extrae. Sin embargo, el comportamiento real de TarFile.errorlevel = 0 en las versiones afectadas es que el miembro se extrae y no se omite.
