There is a LOW severity vulnerability affecting CPython.
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. There is no patch available yet, the CVE will be updated
once there is a fixed version.
