CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 1CVE-2021-4129 – Mozilla: Memory safety bugs fixed in Firefox 95 and Firefox ESR 91.4
https://notcve.org/view.php?id=CVE-2021-4129
Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith, Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 95, Firefox ESR < 91.4.0, and Thunderbird < 91.4.0. Los desarrolladores de Mozilla y miembros de la comunidad Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith, Christian Holler y Masayuki Nakano informaron sobre errores de seguridad de la memoria presentes en Firefox 94.

The <code>ms-msdt</code>, <code>search</code>, and <code>search-ms</code> protocols deliver content to Microsoft applications, bypassing the browser, when a user accepts a prompt. These applications have had known vulnerabilities, exploited in the wild (although we know of none exploited through Thunderbird), so in this release Thunderbird has blocked these protocols from prompting the user to open them.<br>*This bug only affects Thunderbird on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. • https://bugzilla.mozilla.org/show_bug.cgi?id=1773717 https://www.mozilla.org/security/advisories/mfsa2022-24 https://www.mozilla.org/security/advisories/mfsa2022-25 https://www.mozilla.org/security/advisories/mfsa2022-26 •
