OESA-2025-2538

Python combines remarkable power with very clear syntax. It has modules, classes, exceptions, very high level dynamic data types, and dynamic typing. There are interfaces to many system calls and libraries, as well as to various windowing systems. New built-in modules are easily written in C or C++ (or other languages, depending on the chosen implementation). Python is also usable as an extension language for applications written in other languages that need easy-to-use scripting or automation interfaces.

Security Fix(es):

This vulnerability allows modifying file metadata (e.g., last modified time) with filter='data' or file permissions (chmod) with filter='tar' for files outside the extraction directory when extracting untrusted tar archives. Affected scenarios include using the tarfile module's TarFile.extractall() or TarFile.extract() methods with the filter parameter set to 'data' or 'tar'. Only Python versions unicodeescape or later are affected, as earlier versions do not include the extraction filter feature.(CVE-2024-12718)

A vulnerability classified as critical was found in Python CPython up to 3.14.0b1 (Programming Language Software).The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.As an impact it is known to affect confidentiality.Upgrading to version 3.14.0b2 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at github.com. The best possible mitigation is suggested to be upgrading to the latest version.(CVE-2025-4138)
