An update for python-pyinstaller is now available for openEuler-24.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1742 Final 1.0 1.0 2024-06-21 Initial 2024-06-21 2024-06-21 openEuler SA Tool V1.0 2024-06-21 python-pyinstaller security update An update for python-pyinstaller is now available for openEuler-24.03-LTS. PyInstaller bundles a Python application and all its dependencies into a single package. The user can run the packaged app without installing a Python interpreter or any modules. Security Fix(es): PyInstaller bundles a Python application and all its dependencies into a single package. A PyInstaller built application, elevated as a privileged process, may be tricked by an unprivileged attacker into deleting files the unprivileged user does not otherwise have access to. A user is affected if **all** the following are satisfied: 1. The user runs an application containing either `matplotlib` or `win32com`. 2. The application is ran as administrator (or at least a user with higher privileges than the attacker). 3. The user's temporary directory is not locked to that specific user (most likely due to `TMP`/`TEMP` environment variables pointing to an unprotected, arbitrary, non default location). Either: A. The attacker is able to very carefully time the replacement of a temporary file with a symlink. This switch must occur exactly between `shutil.rmtree()`'s builtin symlink check and the deletion itself B: The application was built with Python 3.7.x or earlier which has no protection against Directory Junctions links. The vulnerability has been addressed in PR #7827 which corresponds to `pyinstaller >= 5.13.1`. Users are advised to upgrade. There are no known workarounds for this vulnerability.(CVE-2023-49797) An update for python-pyinstaller is now available for openEuler-24.03-LTS. openEuler Security has rated this update as having a security impact of high.
