CVE-2024-3220

There is a defect in the CPython standard library module “mimetypes” where on Windows the default list of known file locations are writable meaning other users can create invalid files to cause MemoryError to be raised on Python runtime startup or have file extensions be interpreted as the incorrect file type. This defect is caused by the default locations of Linux and macOS platforms (such as “/etc/mime.types”) also being used on Windows, where they are user-writable locations (“C:\etc\mime.types”). To work-around this issue a user can call mimetypes.init() with an empty list (“[]”) on Windows platforms to avoid using the default list of known file locations.

Summary		(es) Hay un defecto en el módulo de la librería estándar CPython “mimetypes” donde en Windows la lista predeterminada de ubicaciones de archivos conocidas son editables, lo que significa que otros usuarios pueden crear archivos no válidos para provocar que se genere MemoryError al iniciar el entorno de ejecución de Python o que las extensiones de archivo se interpreten como el tipo de archivo incorrecto. Este defecto es causado por las ubicaciones predeterminadas de las plataformas Linux y macOS (como “/etc/mime.types”) que también se usan en Windows, donde son ubicaciones editables por el usuario (“C:\etc\mime.types”). Para solucionar este problema, un usuario puede llamar a mimetypes.init() con una lista vacía (“[]”) en las plataformas Windows para evitar usar la lista predeterminada de ubicaciones de archivos conocidas.
