Description
I'm running mc-4.8.25-3.fc33.x86_64.rpm and I've noticed quite a nasty bug:
I've just copied /etc/shadow to a new location at the same file system and the permissions have changed from 000 to 644 which is a critical security bug. The preserve attributes checkbox is enabled:
[x] Preserve attributes
The application is running under root.
If either of user/group/other read/write bits are on, permissions are preserved.
The bug is also reproducible when moving a file to a different filesystem.
