gpac vulnerabilities

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

Ubuntu 18.10
Ubuntu 18.04 LTS
Ubuntu 16.04 LTS

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
memory operations. If an user or automated system were tricked into opening a
specially crafted MP4 file, a remote attacker could use this issue to cause
MP4Box to crash, resulting in a denial of service, or possibly execute
arbitrary code.
