USN-6216-1

It was discovered that lib3mf did not properly manage memory under certain circumstances. If a user were tricked into opening a specially crafted 3MF file, a local attacker could possibly use this issue to cause applications using lib3mf to crash, resulting in a denial of service, or possibly execute arbitrary code.
