Upgrading from 5.7.5.2 to 5.7.5.3

Permalink
Hi

I have tried to update from 5.7.5.2 to 5.7.5.3, but had a few security issues along the way. My environment information says the following:

# concrete5 Version
Core Version - 5.7.5.3
Version Installed - 5.7.5.2
Database Version - 20150731000000

Does this mean that I am on 5.7.5.2 or 5.7.5.3...?
