Managed code usually helps prevent those kinds of attacks.

Not so sure about that, could be a buffer overrun too.

Okay, I've got a strategy for this. The question is asking if the use of MSPs increases a blockchain's vulnerability to Denial of Service attacks. So I need to consider how MSPs might centralize the blockchain and how that could impact its resistance to DoS attacks.
