Affected versions of this package are vulnerable to Race Condition when processes are spawned concurrently from multiple threads. This issue particularly affects the "spawn" method of multiprocessing, which is not thread-safe on Linux.

Execution with Unnecessary Privileges

pyinstaller is a package that bundles a Python application and all its dependencies into a single package

Affected versions of this package are vulnerable to Execution with Unnecessary Privileges. When the tempfile.mkdtemp function is used, it creates a temporary directory that should only be accessible by the creating user ID. However, on Windows systems, the 0o700 POSIX permissions mask has no effect, leading to potential security issues. An attacker with local access can interfere with the application by modifying the contents of the temporary directory if it is located in a system-wide location and the application is running in privileged mode with developer mode enabled. This is only exploitable if the temporary directory base is relocated to a system-wide location (e.g., c:\temp) and developer mode is enabled on the system.

How to fix Execution with Unnecessary Privileges?

Upgrade pyinstaller to version 5.13.1 or higher.
