 Description  « Hide
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.
