CVE-2023-41105 Information

Description

An issue was discovered in Python 3.11 through 3.11.4. If a path containing ‘\0’ bytes is passed to os.path.normpath() the path will be truncated unexpectedly at the first ‘\0’ byte. There are plausible cases in which an application would have rejected a filename for security reasons in Python 3.10.x or earlier but that filename is no longer rejected in Python 3.11.x.
