https://notcve.org/view.php?id=CVE-2023-6860
The `VideoBridge` allowed any content process to use textures produced by remote decoders. This could be abused to escape the sandbox. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121. El "VideoBridge" permitía que cualquier proceso de contenido utilizara texturas producidas por decodificadores remotos. Se podría abusar de esto para escapar de la sandbox. • https://bugzilla.mozilla.org/show_bug.cgi?id=1854669 https://lists.debian.org/debian-lts-announce/2023/12/msg00020.html https://lists.debian.org/debian-lts-announce/2023/12/msg00021.html https://security.gentoo.org/glsa/202401-10 https://www.debian.org/security/2023/dsa-5581 https://www.debian.org/security/2023/dsa-5582 https://www.mozilla.org/security/advisories/mfsa2023-54 https://www.mozilla.org/security/advisories/mfsa2023-55 https://www.mozilla.org/security/advisories/mf • CWE-20: Improper Input Validation •
