Thank you for taking the time to report this issue to us. We appreciate the feedback and use reports such as this one to guide our efforts at improving our products. That being said, this bug tracking system is not a mechanism for requesting support, and we are not able to guarantee the timeliness or suitability of a resolution. If this issue is critical or in any way time sensitive, please raise a ticket through the regular Red Hat support channels to ensure it receives the proper attention and prioritization to assure a timely resolution. For information on how to contact the Red Hat production support team, please visit: https://www.redhat.com/support/process/production/#howto For proper identification of issue are required properly filled following information: - Description of problem - Version-Release number of selected component (if applicable) - Steps to Reproduce - Actual results - Expected results - Additional info Issues reported in bug 1485286 and bug 1485280 were now reported upstream via: https://github.com/mdadams/jasper/issues/165 Note that the relevant assert()s were added in jasper 2.0.12 and don't exist in the jasper packages in Red Hat Enterprise Linux 7 (the product this bug is reported against). This vulnerability was evaluated by the sub-system, taking into account the kind of the component, and its use cases. It was not considered as a priority for the next release, so it's being closed now as WONTFIX.
