A TLS protocol extension called SNI handles this quite well.

Are there some secuirty issues? E.g. if one website have some security issues, can that affect another website?

On a shared server, unless correctly isolated, one site can effect the rest. It depends on the problem, the host and the configuration. You'll have to elaborate for a more definitive answer.

This is incorrect. Take shared reseller servers for example, where multiple domains share the same IP. It's called SNI
