https://notcve.org/view.php?id=CVE-2020-15658
The code for downloading files did not properly take care of special characters, which led to an attacker being able to cut off the file ending at an earlier position, leading to a different file type being downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. El código para descargar archivos no toma cuidado apropiadamente de los caracteres especiales, lo que conllevaba a que un atacante sea capaz de cortar el archivo que terminaba en una posición anterior, conllevando a que sea descargado un tipo de archivo diferente al mostrado en el cuadro de diálogo. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 78.1, Firefox versiones anteriores a 79 y Thunderbird versiones anteriores a 78.1 • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html https://bugzilla.mozilla.org/show_bug.cgi?id=1637745 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-32 https://www.mozilla.org/security/advisories/mfsa2020-33 https://access.redhat.com/security/cve/CVE-2020-15658 https://bugzilla.redhat.com/show_bug.cgi?id=1861647 • CWE-138: Improper Neutralization of Special Elements CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2020-15653
An iframe sandbox element with the allow-popups flag could be bypassed when using noopener links. This could have led to security issues for websites relying on sandbox configurations that allowed popups and hosted arbitrary content. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. Un elemento del sandbox de iframe con el flag allow-popups podría ser omitida cuando se usan enlaces noopener. Esto podría haber conllevado a problemas de seguridad para los sitios web que dependen de configuraciones de sandbox que permitían ventanas emergentes y alojaban contenido arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html https://bugzilla.mozilla.org/show_bug.cgi?id=1521542 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-32 https://www.mozilla.org/security/advisories/mfsa2020-33 https://access.redhat.com/security/cve/CVE-2020-15653 https://bugzilla.redhat.com/show_bug.cgi?id=1861645 • CWE-276: Incorrect Default Permissions •

https://notcve.org/view.php?id=CVE-2020-15654
When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user is interacting with the user interface, when they are not. This could lead to a perceived broken state, especially when interactions with existing browser dialogs and warnings do not work. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1. Cuando en un bucle infinito, un sitio web que especifica un cursor personalizado usando CSS podría hacer que parezca que el usuario está interactuando con la interfaz de usuario, cuando no es así. Esto podría conllevar a un estado roto percibido, especialmente cuando las interacciones con los diálogos y advertencias del navegador existentes no funcionan. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html https://bugzilla.mozilla.org/show_bug.cgi?id=1648333 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-32 https://www.mozilla.org/security/advisories/mfsa2020-33 https://access.redhat.com/security/cve/CVE-2020-15654 https://bugzilla.redhat.com/show_bug.cgi?id=1861649 • CWE-451: User Interface (UI) Misrepresentation of Critical Information CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
