Can Sandboxie protect user and itself from RAM attacks?

[Lumberjack]

First of all I don't know what exactly are RAM attacks, but yesterday I heard it from an programmer, so what's the big deal here?

I wonder exactly the same thing. If it is possible for a sandboxed process to write into memory areas of unsandboxed programms, then a malware inside a sandbox could inject malicious code into other processes. I'd like to hear a statement on this from the SandboxIE programmer.

That´s not possible.

That´s not possible.

Could you be more specific?

It is not possible that a sandboxed process writes to memory areas of an unsandboxed program.

If this was possible, lots of malware would infect the system.
