This is a bug for fixing SAST findings for net-tools component. There are a couple of findings that I think I can fix. There are also a couple that I believe are not worth fixing. net-tools has been deprecated for more than 30 years now and there is no Upstream where I could ask how was a certain piece of code intended to be used. I will add my findings and solutions in the comments.
