When encoding a legacy ESTABLISH_INTRO cell, we were using the sizeof() on a pointer instead of using the real size of the destination buffer leading to an overflow passing an enormous value to the signing digest function. Fortunately, that value was only used to make sure the destination buffer length was big enough for the key size and in this case it always was because of the overflow.
