For example:a = []for i in range(22): a = [a, a]b = plistlib.dumps(a, fmt=plistlib.FMT_BINARY)The result is 130 bytes long on patched plistlib. But plistlib.dumps(b) will expand to a structure consuming almost a gigabyte of memory on unpatched plistlib. Increasing the level of nesting by one will duplicate memory consumption, so it is easy to consume all available memory on any computer. |
