One way to help mitigate that is by tiering releases. Rather than deploying an app that can potentially accept millions of dollars on day 1, it can be purposely limited to lower amounts and slowly increased over time as the codebase is iterated and time-tested. Apps that have been around for decades with few changes are significantly safer than new apps. Of course this is not perfect (ie heartbleed) but I think this methodology will become standard in ethereum.
