> While reading the ASN.1 decoder code, I found a pretty nasty case where the decoding
can fail during length decoding :
> if the length is more than 2 bytes long, and if the PDU is splitted just after the second
byte, then we can have a BufferUnderFlowException.
> This can occur because we are reading the buffe without controlling that we still have
some remaining bytes.
