Turbo code interleaver attack

I wonder if the deterministic nature of most turbo code interleavers may form the basis of an attack, for example, a Denial-of-service attack where carefully corrupted packets induce worst-case computational load (maximum number of iterations to achieve convergence) thereby causing your 3G cell phone to quickly run out of battery.

Or, a stupidly designed cryptographic cipher combined with an error-correcting code where again carefully corrupted packets, and requests for retransmissions, reveal information about the secret payload.
