Moving away from C just means you now have to have faith in some bytecode virtual machine's memory and buffer management. Is it a more secure approach? Maybe, but if the root complaint is putting faith in complex software, coding in Java or some .NET language means trusting the people coding those engines are equally capable of screwing up. All these higher level virtual machines and interpreters are ultimately written in C.

All I know is the organization I work for has prohibited use of C or C++ for mission critical software for years now. The languages we use would not ALLOW code to execute which tries to copy 64K from a 2 byte sized container.

Still it surprises me that security software can be modified so quickly and with only one review

The RT line, with the ARM chips (like what this whole story is about) are not doing so well.
