https://notcve.org/view.php?id=CVE-2020-12418
Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0. La manipulación de partes individuales de un objeto URL podría haber causado una lectura fuera de límites, filtrando la memoria de proceso a un JavaScript malicioso. Esta vulnerabilidad afecta a Firefox ESR versiones anteriores a 68.10, Firefox versiones anteriores a 78 y Thunderbird versiones anteriores a 68.10.0 The Mozilla Foundation Security Advisory describes this flaw as: Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00026.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00049.html https://bugzilla.mozilla.org/show_bug.cgi?id=1641303 https://security.gentoo.org/glsa/202007-09 https://security.gentoo.org/glsa/202007-10 https://usn.ubuntu.com/4421-1 https://www.mozilla. • CWE-125: Out-of-bounds Read CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2020-12415
When "%2F" was present in a manifest URL, Firefox's AppCache behavior may have become confused and allowed a manifest to be served from a subdirectory. This could cause the appcache to be used to service requests for the top level directory. This vulnerability affects Firefox < 78. Cuando "%2F" estaba presente en una URL de manifiesto, el comportamiento de AppCache de Firefox puede haber sido confundido y permitir que sea servido un manifiesto desde un subdirectorio. Esto podría hacer que el appcache sea usado para atender peticiones para el directorio de nivel superior. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00049.html https://bugzilla.mozilla.org/show_bug.cgi?id=1586630 https://security.gentoo.org/glsa/202007-10 https://www.mozilla.org/security/advisories/mfsa2020-24 • CWE-276: Incorrect Default Permissions •
CVSS: 6.5EPSS: 0%CPEs: 3EXPL: 0CVE-2020-12424 – Mozilla: WebRTC permission prompt could have been bypassed by a compromised content process
https://notcve.org/view.php?id=CVE-2020-12424
When constructing a permission prompt for WebRTC, a URI was supplied from the content process. This URI was untrusted, and could have been the URI of an origin that was previously granted permission; bypassing the prompt. This vulnerability affects Firefox < 78. Cuando se construye un aviso de permiso para WebRTC, se suministraba un URI desde el proceso de contenido. Este URI no era confiable, y podría haber sido el URI de un origen que previamente se le concediera permiso; omitiendo el aviso. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00049.html https://bugzilla.mozilla.org/show_bug.cgi?id=1562600 https://security.gentoo.org/glsa/202007-10 https://www.mozilla.org/security/advisories/mfsa2020-24 https://access.redhat.com/security/cve/CVE-2020-12424 https://bugzilla.redhat.com/show_bug.cgi?id=1872539 • CWE-276: Incorrect Default Permissions CWE-451: User Interface (UI) Misrepresentation of Critical Information •
