https://notcve.org/view.php?id=CVE-2020-15664
By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80. Al mantener una referencia a la función eval() desde una ventana about:blank, una página web maliciosa podría haber conseguido acceso al objeto InstallTrigger, lo que le permitiría solicitar al usuario que instale una extensión. Combinado con la confusión del usuario, esto podría resultar en la instalación de una extensión maliciosa o involuntaria. • https://bugzilla.mozilla.org/show_bug.cgi?id=1658214 https://www.mozilla.org/security/advisories/mfsa2020-36 https://www.mozilla.org/security/advisories/mfsa2020-37 https://www.mozilla.org/security/advisories/mfsa2020-38 https://www.mozilla.org/security/advisories/mfsa2020-39 https://www.mozilla.org/security/advisories/mfsa2020-40 https://www.mozilla.org/security/advisories/mfsa2020-41 https://access.redhat.com/security/cve/CVE-2020-15664 https://bugzilla.redhat.com/show_bug.cgi?id=1872 • CWE-648: Incorrect Use of Privileged APIs CWE-863: Incorrect Authorization •

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 •
