A specially crafted MPEG-4 input can cause an integer overflow when the library encounters an atom using the “trun” 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.", "severity": [ { "type": "CVSS_V3", "score": "CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H" } ], "affected": [], "references": [ { "type": "ADVISORY", "url": "https://nvd.nist.gov/vuln/detail/CVE-2021-21850" }, { "type": "WEB", "url": "https://talosintelligence.com/vulnerability_reports/TALOS-2021-1297" }, { "type": "WEB", "url": "https://www.debian.org/security/2021/dsa-4966" } ], "database_specific": { "cwe_ids": [ "CWE-190" ], "severity": "HIGH", "github_reviewed": false, "github_reviewed_at": null, "nvd_published_at": "2021-08-25T19:15:00Z" } }
