CVE-2020-26954
https://notcve.org/view.php?id=CVE-2020-26954

This could be used to gain fullscreen access for UI spoofing and could also lead to cross-origin attacks on targeted websites. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83. • https://bugzilla.mozilla.org/show_bug.cgi?id=1657026 https://www.mozilla.org/security/advisories/mfsa2020-50 •

CVE-2020-26958 – Mozilla: Requests intercepted through ServiceWorkers lacked MIME type restrictions
https://notcve.org/view.php?id=CVE-2020-26958
Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. Firefox no bloqueó una ejecución de scripts con tipos MIME incorrectos cuando la respuesta fue interceptada y almacenada en caché por medio de un ServiceWorker. Esto podría conllevar a una vulnerabilidad de inclusión de cross-site script, o una omisión de Content Security Policy. • https://bugzilla.mozilla.org/show_bug.cgi?id=1669355 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-2020-26958 https://bugzilla.redhat.com/show_bug.cgi?id=1898735 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-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 •
CVE-2020-26960 – Mozilla: Potential use-after-free in uses of nsTArray
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 •
