Browser vulnerabilities

I just don't understand something... I know how some vulnerabilities in internet browsers work... There is a lot of flaws that can allow remote code execution in different ways... they can be blocked with something like noscript... most of the times....


But, I don't understand when I read that a page will redirect you to a malicious web page (it's ok for this...) and will download and install a malicious program... I mean... Is it possible to download a file without user intervention?? And if it is... It can be executed without any user action

Thanks
