Security holes and vulnerabilities in 1.5

I have a customer who recently got her 1.5.3.1 hacked. It is uncertain how the spread got in.

I found a list of vulnerabilities in 1.5.2.1 at http://www.waraxe.us/advisory-84.html. Is it legit, and have the vulnerabilities been plugged?

Are there any known vulnerabilities in 1.5.3.1?

Is there a page out there for keeping an eye on opencart vulnerabilities status?

I had seen that quite a long time ago. It's been dismissed as not possible, chances are only in windows server, but already patched in 1.5.3.1.
