5c82f67012 avcodec/qdrw: Fix null pointer dereference 
The RGB555 PACKBITSRGN case tries to read a palette, if such
palette is actually stored then it accesses a null pointer.
All 16bit samples i could find use DIRECTBITSRGN.

e18bd51596 avcodec/libfdk-aacdec: Correct buffer_size parameter 
the timeDataSize argument to aacDecoder_DecodeFrame() seems undocumented and until
2016 04 (203e3f28fbebec7011342017fafc2a0bda0ce530) unused.
after that commit libfdk-aacdec interprets it as size in sample units and memsets that on error.
FFmpeg as well as others (like GStreamer) did interpret it as size in bytes

Fixes: 1442/clusterfuzz-testcase-minimized-4540199973421056 (This requires recent libfdk to reproduce)
