The rcwt muxer uses several counters for how much data it has already cached: One byte counter and one counter for how many complete blocks (of three bytes each). These counters can become inconsistent when the muxer is fed incomplete blocks as the muxer presumes that it is about to write a new block at the start of each write_packet call. E.g. sending 65535*3+1 1-byte packets (with data[0] e.g. 0x03) will trigger an out-of-bounds write. This patch fixes this by processing the data in complete blocks only. This also allows to simplify the code, e.g. to remove one of the counters. Reviewed-by: Marth64 <marth64@proxyid.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
