Description Prasad Pandit 2021-01-23 12:56:12 UTC 
Description of problem:

Consider the following commands, executed as root:

# mount --bind -o noexec /bin /mnt
# /mnt/ls

The expected behavior is the following:

bash: /mnt/ls: Permission denied

This is what happens on Fedora 33.

On both RHEL7 and RHEL8, the "ls" utility is executed.


How reproducible:  100%
