CVE-2023-41105 (GCVE-0-2023-41105)

Vulnerability from cvelistv5 – Published: 2023-08-23 00:00 – Updated: 2024-10-03 14:04
VLAI
Summary
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.
Severity
No CVSS data available.
