The library will actually reuse the parser for atoms with the \u00e2\u20ac\u0153stsz\u00e2\u20ac\ufffd FOURCC code when parsing atoms that use the \u00e2\u20ac\u0153stz2\u00e2\u20ac\ufffd FOURCC code and can cause an integer overflow 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": "2021-08-25T22:25:55.000000Z"} 2021-08-25T22:25:55+00:00
