The issue is caused by yr_re_fast_exec overflowing and returning a negative length which is used to build a Python bytes object here: https://github.com/VirusTotal/yara-python/blob/7e19b740b301c097609a42930338498324d130c8/yara-python.c#L929 The object creation fails later PY_DECREF trips because the refcount would go negative.
yr_re_fast_exec
PY_DECREF
The original issue is fixed by https://github.com/VirusTotal/yara/pull/1615, so updating the yara submodule would fix this issue too.
