python is vulnerable to Untrusted Search Path. The vulnerability is due to the _Py_normpath function which cannot process paths with embedded null characters without truncating the path. If a path containing the \0 byte is passed to os.path.normpath(), the path will be truncated unexpectedly at the first \0 byte. An attacker can exploit this behavior by constructing a path with null bytes, which will be unexpectedly truncated at the first \0 byte.
