Similar to the CVE-2016-9390 issue, the impact of this flaw seems to be limited to triggering various assertion failures. Failed assertion causes program to exit unexpectedly, but does not allow code execution. As a precaution against impacts other than the known assertion failures, it may get addressed in future jasper packages in Red Hat Enterprise Linux 6 and 7.
