There is a very minor DCC exploit in 6.12 (and probably 6.14 too) that can only be executed under very specific circumstances. It is nowhere near as bad as the one present in 6.0 -> 6.11. It is close to impossible to be crashed with 6.12 and above.
For further information, and some code to protect yourself if you're still worried someone can crash you,
read this It's nothing to worry about though
