Mozilla developers reported memory safety bugs present in Firefox for Android 79. 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 < 80, Firefox ESR < 78.2, Thunderbird < 78.2, and Firefox for Android < 80. Los desarrolladores de Mozilla reportaron de unos bugs de seguridad de la memoria presentes en Firefox para Android versión 79.

CVSS: 6.1EPSS: 0%CPEs: 7EXPL: 0CVE-2020-15676 – Mozilla: XSS when pasting attacker-controlled data into a contenteditable element
https://notcve.org/view.php?id=CVE-2020-15676
Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove, resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. Firefox a veces ejecutaba el manejador de carga para elementos SVG que el saneador DOM decidió eliminar, resultando en que el JavaScript sea ejecutado después de pegar los datos controlados por el atacante en un elemento satisfactorio. Esta vulnerabilidad afecta a Firefox versiones anteriores a 81, Thunderbird versiones anteriores a 78.3, y Firefox ESR versiones anteriores a 78.3 The Mozilla Foundation Security Advisory describes this flaw as: Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove, resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable element. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00074.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00077.html https://bugzilla.mozilla.org/show_bug.cgi?id=1646140 https://lists.debian.org/debian-lts-announce/2020/10/msg00020.html https://security.gentoo.org/glsa/202010-02 https://www.debian.org/security/2020/dsa-4770 https://www.mozilla.org/security/advisories/mfsa2020-42 https://www.mozilla.org/security/advisories/mfsa2020-43 https://www.mozil • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVSS: 8.8EPSS: 0%CPEs: 7EXPL: 0CVE-2020-15678 – Mozilla: When recursing through layers while scrolling, an iterator may have become invalid, resulting in a potential use-after-free scenario
https://notcve.org/view.php?id=CVE-2020-15678
When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in a potential use-after-free. This occurs because the function APZCTreeManager::ComputeClippedCompositionBounds did not follow iterator invalidation rules. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. Al volver a recorrer las capas gráficas mientras se desplaza, es posible que un iterador pueda convertirse en no válido, resultando en un potencial uso de la memoria previamente liberada. Esto ocurre porque la función APZCTreeManager::ComputeClippedCompositionBounds no siguió las reglas de invalidación del iterador. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00074.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00077.html https://bugzilla.mozilla.org/show_bug.cgi?id=1660211 https://lists.debian.org/debian-lts-announce/2020/10/msg00020.html https://security.gentoo.org/glsa/202010-02 https://www.debian.org/security/2020/dsa-4770 https://www.mozilla.org/security/advisories/mfsa2020-42 https://www.mozilla.org/security/advisories/mfsa2020-43 https://www.mozil • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-15677
By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. Al explotar una vulnerabilidad de Redireccionamiento Abierto en un sitio web, un atacante podría haber falsificado el sitio que es mostrado en el cuadro de diálogo del archivo de descarga para mostrar el sitio original (el que sufre el redireccionamiento abierto) en lugar del sitio del que se descargó el archivo realmente. Esta vulnerabilidad afecta a Firefox versiones anteriores a 81, Thunderbird versiones anteriores a 78.3, y Firefox ESR versiones anteriores a 78.3 The Mozilla Foundation Security Advisory describes this flaw as: By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site displayed in the download file dialog to show the original site (the one suffering from the open redirect) rather than the site the file was actually downloaded from. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00074.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00077.html https://bugzilla.mozilla.org/show_bug.cgi?id=1641487 https://lists.debian.org/debian-lts-announce/2020/10/msg00020.html https://security.gentoo.org/glsa/202010-02 https://www.debian.org/security/2020/dsa-4770 https://www.mozilla.org/security/advisories/mfsa2020-42 https://www.mozilla.org/security/advisories/mfsa2020-43 https://www.mozil • CWE-601: URL Redirection to Untrusted Site ('Open Redirect') •
