CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-26965 – Mozilla: Software keyboards may have remembered typed passwords
https://notcve.org/view.php?id=CVE-2020-26965
Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. Algunos sitios web presentan una funcionalidad "Show Password" donde al hacer clic en un botón se cambiará un campo de contraseña en un campo textbook, divulgando la contraseña escrita. Si, al usar un teclado de software que recuerda la entrada del usuario, un usuario escribió su contraseña y usó esa funcionalidad, se cambió el tipo de campo de contraseña, resultando en un cambio de distribución del teclado y la posibilidad de que el teclado de software recuerde la contraseña escrita. • https://bugzilla.mozilla.org/show_bug.cgi?id=1661617 https://www.mozilla.org/security/advisories/mfsa2020-50 https://www.mozilla.org/security/advisories/mfsa2020-51 https://www.mozilla.org/security/advisories/mfsa2020-52 https://access.redhat.com/security/cve/CVE-2020-26965 https://bugzilla.redhat.com/show_bug.cgi?id=1898739 • CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •

https://notcve.org/view.php?id=CVE-2020-26960
If the Compact() method was called on an nsTArray, the array could have been reallocated without updating other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. Si el método Compact() fue llamado en un nsTArray, el array podría haber sido reasignado sin actualizar otros punteros, conllevando a un potencial uso de la memoria previamente liberada y un bloqueo explotable. Esta vulnerabilidad afecta a Firefox versiones anteriores a 83, Firefox ESR versiones anteriores a 78.5, y Thunderbird versiones anteriores a 78.5 • https://bugzilla.mozilla.org/show_bug.cgi?id=1670358 https://www.mozilla.org/security/advisories/mfsa2020-50 https://www.mozilla.org/security/advisories/mfsa2020-51 https://www.mozilla.org/security/advisories/mfsa2020-52 https://access.redhat.com/security/cve/CVE-2020-26960 https://bugzilla.redhat.com/show_bug.cgi?id=1898737 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-26953
It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. Fue posible causar que el navegador entre en modo de pantalla completa sin mostrar la interfaz de seguridad, lo que permite intentar un ataque de phishing o confundir de alguna manera al usuario.

CVSS: 6.1EPSS: 0%CPEs: 3EXPL: 0CVE-2020-26951 – Mozilla: Parsing mismatches could confuse and bypass security sanitizer for chrome privileged code
https://notcve.org/view.php?id=CVE-2020-26951
A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. Un desajuste en el análisis y la carga de eventos en el código SVG de Firefox podría haber permitido a unos eventos de carga dispararse, incluso después del saneamiento. Un atacante ya capaz de explotar una vulnerabilidad de tipo XSS en páginas internas privilegiadas podría haber usado este ataque para omitir nuestro sanitizador incorporado. • https://bugzilla.mozilla.org/show_bug.cgi?id=1667113 https://www.mozilla.org/security/advisories/mfsa2020-50 https://www.mozilla.org/security/advisories/mfsa2020-51 https://www.mozilla.org/security/advisories/mfsa2020-52 https://access.redhat.com/security/cve/CVE-2020-26951 https://bugzilla.redhat.com/show_bug.cgi?id=1898731 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') CWE-354: Improper Validation of Integrity Check Value •
