In the slow literal copy path, it wasn't validating that the literal fit within the input buffer, so the call to copyMemory could read from out of bounds and cause a crash. When copying a match, it wasn't validating that the match fit within the output buffer in both branches (slow & fast path), so the operation could write outside of the output buffer if the match length was corrupted.
