A specially crafted MPEG-4 input can cause an integer overflow when the library encounters an atom using the \u00e2\u20ac\u0153trun\u00e2\u20ac\ufffd FOURCC code due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. An attacker can convince a user to open a video to trigger this vulnerability.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2021-08-25T22:26:03.000000Z"}]}
