  • Write a fuzzer that fuzzes all the helper functions that take compressed input.
  • Found an out-of-bounds read in ZSTD_decompressBound().
  • Fix a bug where ZSTD_findDecompressedSize() would return a zstd error code if readSkippableFrameSize() failed.

Add a fuzzer that fuzzes all helper functions that take compressed
