A 64-byte STATUS_MORE_PROCESSING_REQUIRED SESSION_SETUPresponse is therefore accepted even though it cannot contain theSecurityBufferOffset and SecurityBufferLength fields.\nThe parser then reads those fields from stale bytes left in the reusedreceive buffer by an earlier frame. With a long staleSecurityBufferLength, decode_ntlmssp_challenge() copies up to about64 KB from beyond the receive object and sends the data back to theserver in the NTLMv2 AUTHENTICATE target info.\nReject short MPR SESSION_SETUP responses before the short-error path,and validate SecurityBufferOffset + SecurityBufferLength against thereceived response length before decoding the challenge.\nThe ordering bypass is not new: the short-error early return predatesb4694f269e66d, and the unvalidated SecurityBufferLength read predatesthe 2016 raw NTLMSSP split in 166cea4dc3a4, so all supported stabletrees are affected.
