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. Algunos de estos errores mostraron evidencia de corrupción de la memoria y suponemos que con suficiente esfuerzo algunos de estos podrían haber sido explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1393362%2C1736046%2C1736751%2C1737009%2C1739372%2C1739421 https://www.mozilla.org/security/advisories/mfsa2021-52 https://www.mozilla.org/security/advisories/mfsa2021-53 https://www.mozilla.org/security/advisories/mfsa2021-54 https://access.redhat.com/security/cve/CVE-2021-4129 https://bugzilla.redhat.com/show_bug.cgi?id=2030116 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2022-34478
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 •
CVSS: 8.1EPSS: 0%CPEs: 1EXPL: 0CVE-2022-45414 – Mozilla: Quoting from an HTML email with certain tags will trigger network requests and load remote content, regardless of a configuration to block remote content
https://notcve.org/view.php?id=CVE-2022-45414
If a Thunderbird user quoted from an HTML email, for example by replying to the email, and the email contained either a VIDEO tag with the POSTER attribute or an OBJECT tag with a DATA attribute, a network request to the referenced remote URL was performed, regardless of a configuration to block remote content. An image loaded from the POSTER attribute was shown in the composer window. These issues could have given an attacker additional capabilities when targetting releases that did not yet have a fix for CVE-2022-3033 which was reported around three months ago. This vulnerability affects Thunderbird < 102.5.1. The Mozilla Foundation Security Advisory describes this flaw as: If a Thunderbird user quoted from an HTML email and the email contained either a video tag with the poster attribute or an object tag with a data attribute, a network request to the referenced remote URL was performed regardless of a configuration to block remote content, and an image loaded from the poster attribute was shown in the composer window. • https://bugzilla.mozilla.org/show_bug.cgi?id=1788096 https://www.mozilla.org/security/advisories/mfsa2022-50 https://access.redhat.com/security/cve/CVE-2022-45414 https://bugzilla.redhat.com/show_bug.cgi?id=2149868 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
