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.

Bug
Closed
Major
Decoding of lengths can fail if the PDU is splitted
- we must have a PDU which is more than 256 bytes long
- and the length part should be splitted
However, this is still a serious bug (and easy to fix :). Code reviews are *good*
