CVSS: 6.5EPSS: 0%CPEs: 7EXPL: 0CVE-2020-12421 – Mozilla: Add-On updates did not respect the same certificate trust rules as software updates
https://notcve.org/view.php?id=CVE-2020-12421
When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0. Cuando se llevan a cabo actualizaciones de add-on, las cadenas de certificados que terminan en non-built-in-roots fueron rechazadas (incluso si fueron agregadas legítimamente por un administrador). Esto podría haber causado que los add-ons se desactualicen silenciosamente sin notificación al usuario. • 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=1308251 https://security.gentoo.org/glsa/202007-09 https://security.gentoo.org/glsa/202007-10 https://usn.ubuntu.com/4421-1 https://www.mozilla. • CWE-295: Improper Certificate Validation CWE-296: Improper Following of a Certificate's Chain of Trust •
CVSS: 6.5EPSS: 0%CPEs: 1EXPL: 0CVE-2020-12425 – Mozilla: Out of bound read in Date.parse()
https://notcve.org/view.php?id=CVE-2020-12425
Due to confusion processing a hyphen character in Date.parse(), a one-byte out of bounds read could have occurred, leading to potential information disclosure. This vulnerability affects Firefox < 78. Debido a una confusión al procesar un carácter hyph en la función Date.parse(), podría haber ocurrido una lectura fuera de límites de un byte, conllevando a una potencial divulgación de información. Esta vulnerabilidad afecta a Firefox versiones anteriores a 78 • 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=1634738 https://security.gentoo.org/glsa/202007-10 https://www.mozilla.org/security/advisories/mfsa2020-24 https://access.redhat.com/security/cve/CVE-2020-12425 https://bugzilla.redhat.com/show_bug.cgi?id=1872540 • CWE-125: Out-of-bounds Read •
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 •

Mozilla developers and community members reported memory safety bugs present in Firefox 77. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 78.

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 •
