==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 18.10

Summary:
GPAC could be made to crash or run programs as your login if it
opened a specially crafted file.
Software Description:
– gpac: GPAC Project on Advanced Content
Details:
It was discovered that the GPAC MP4Box utility incorrectly handled certain

arbitrary code.
