Check for integer overflow in AesTask::DoCrypto() (DiD)
After calling mResult.SetLength(mData.Length() + 16) we should check
that the integer addition didn't overflow. It seems at the moment
impossible to create ArrayBuffers of size >= 0x0xfffffff0, however
adding a check here doesn't hurt.
mResult.Length() is passed to the PK11 API functions as a
maxOut parameter and should be checked by the
softoken crypto algorithm implementations.
AES-ECB and AES-GCM seem to do that correctly.
