Subject: jasper: multiple assertion failures

If it is suitable for a CVE please assign one. Thanks.

Description:
jasper is an open-source initiative to provide a free software-based reference 
implementation of the codec specified in the JPEG-2000 Part-1 standard.

A fuzzing revealed multiple assertion failures.
Since the jasper’s maintainer releases frequently, the fuzzing was done across 
multiple versions. The “affected version” tag means that it was tested and 
discovered on that version, so previously versions may be affected too.
The latest failures are unfixed. I will update the post when upstream will 
work on them.
