About

The Python launcher for Windows is a utility which aids in locating and executing of different Python versions.

It allows scripts (or the command-line) to indicate a preference for a specific Python version, and will locate and execute that version.

Unlike the PATH variable, the launcher will correctly select the most appropriate version of Python.

It will prefer per-user installations over system-wide ones, and orders by language version rather than using the most recently installed version.

The launcher was originally specified in PEP 397.

    Stack-based buffer overflow in the file_compress function in minigzip (Modules/zlib) in Python 2.5 allows context-dependent attackers to execute arbitrary code via a long file argument.

Source: NVD, updated 5h ago. Patch status is best-effort: NVD's fix version is compared against the latest version in winget, but the two version formats don't always align. Confirm with the vendor advisory before treating any specific build as safe.
