- libmpg123:
- Better checks for xrpnt overflow in III_dequantize_sample() before each use, avoiding false positives and catching cases that were rendered harmless by alignment-enlarged buffers.
- Prevent harmless call to memcpy(NULL, NULL, 0).
- More early checking of ID3v2 encoding values to avoid bogus text being stored.
