The logic in general_bad_file_permissions seems to ignore stat.S_IXOTH (execute by others), which is the most dangerous of all the POSIX file flags.

It raises a high severity issue for S_IWOTH (write by others) and it raises a medium severity issue for S_IXGRP (execute by group).

The following test raises no issues:

import os
import stat

os.chmod('/path/to/binary/i/just/uploaded', stat.S_IXOTH)
