Thanyou both AndrzejL
for your feedback. We do ignore this guy, he wants his 15 mins of fame, every day. He's also someone who taught me stuff ten years ago, when he was more lucid, who I wouldn't like to upset.
Thanks especially Texstar
for taking time to reply. It's a simple black and white scenario you've painted.
A local exploit for the everyday home Linux user requires someone to be in front of your computer to execute.
A remote exploit is a serious matter. A remote exploit would allow someone to get access to your computer without being in front of it and able to get root access. These types of exploits are far and few.
I'm sure you both can understand I don't want people scaring Linux users about Remote Exploits. I doubt saying anything to Polonus will stop him, and that most people can figure he means unwell, while trying to mean well, if that makes any sense.
His method of posting links to complex discussions confuses the reader who is left to wade through too much info and simply end up believing him due to lack of understanding of the content.
Personally I know very little about Linux Security, except the basics.
I may lock this Topic, I don't think there's a lot more to contribute.
If PCLinuxOS users want to get dark and dirty about Linux security, especially 'single user mode', another thread should be created. Maybe it's time.
