ping: permission denied (are you root?) flooding y

I don't know if this is a bug but today I got a weird result that can be easily reproduced.

I created a container with `--cap-drop=ALL` with the image 10.16.3-alpine.
Soon after I accessed the container terminal with the command:
`docker exec -ti CONTAINER_ID / bin/sh` and I used a basic command:
`ping www.google.com`
I got the result
`ping: permission denied (are you root?)`
out of curiosity I tried
`ping www.google.com && yes` or `ping www.google.com; yes`
I received an absurd flood of the letter Y without stopping on my console. I had to restart my machine to get out of the infinite loop.

I believe that if this has no connection to the alpine image or cannot be resolved, I think the phrase (are you root?) Should be removed.
