USN-3926-1: GPAC vulnerabilities

Releases

• Ubuntu 18.10
• Ubuntu 18.04 ESM
• Ubuntu 16.04 ESM

Packages

• 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.
