CVSS: 6.5EPSS: 0%CPEs: 2EXPL: 0CVE-2019-11748 – Mozilla: Persistence of WebRTC permissions in a third party context
https://notcve.org/view.php?id=CVE-2019-11748
WebRTC in Firefox will honor persisted permissions given to sites for access to microphone and camera resources even when in a third-party context. In light of recent high profile vulnerabilities in other software, a decision was made to no longer persist these permissions. This avoids the possibility of trusted WebRTC resources being invisibly embedded in web content and abusing permissions previously given by users. Users will now be prompted for permissions on each use. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1564588 https://www.mozilla.org/security/advisories/mfsa2019-25 https://www.mozilla.org/security/advisories/mfsa2019-26 https://access.redhat.com/security/cve/CVE-2019-11748 https://bugzilla.redhat.com/show_bug.cgi?id=1748665 • CWE-281: Improper Preservation of Permissions CWE-732: Incorrect Permission Assignment for Critical Resource •
CVSS: 4.3EPSS: 0%CPEs: 2EXPL: 0CVE-2019-11749 – Mozilla: Camera information available without prompting using getUserMedia
https://notcve.org/view.php?id=CVE-2019-11749
A vulnerability exists in WebRTC where malicious web content can use probing techniques on the getUserMedia API using constraints to reveal device properties of cameras on the system without triggering a user prompt or notification. This allows for the potential fingerprinting of users. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1. Se presenta una vulnerabilidad en WebRTC donde el contenido web malicioso puede utilizar técnicas de sondeo en la API getUserMedia usando restricciones para revelar las propiedades del dispositivo de las cámaras en el sistema sin la activación de un aviso o notificación de usuario. Esto permite la posible toma de huellas digitales de usuarios. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1565374 https://www.mozilla.org/security/advisories/mfsa2019-25 https://www.mozilla.org/security/advisories/mfsa2019-26 https://access.redhat.com/security/cve/CVE-2019-11749 https://bugzilla.redhat.com/show_bug.cgi?id=1748666 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

https://notcve.org/view.php?id=CVE-2019-11740
Mozilla developers and community members reported memory safety bugs present in Firefox 68, Firefox ESR 68, and Firefox 60.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron bugs de seguridad de la memoria presentes en Firefox versión 68, Firefox ESR versión 68 y Firefox 60.8.

https://notcve.org/view.php?id=CVE-2019-11743
Navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history through timing side-channel attacks. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. Los eventos de navegación no se adhirieron totalmente a la especificación borrador del "Navigation-Timing Level 2" de W3C en algunas instancias para el evento de descarga, que restringe el acceso a los atributos de sincronización detallados para que solo sean del mismo origen. Esto resultó en una posible exposición de información de origen cruzado mediante la sincronización de ataques de canal lateral. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00010.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1560495 https://security.gentoo.org/glsa/201911-07 https://usn.ubuntu.com/4150-1 https://w3c.github.io/navigation-timing https://www.mozilla.org • CWE-203: Observable Discrepancy CWE-829: Inclusion of Functionality from Untrusted Control Sphere •

https://notcve.org/view.php?id=CVE-2019-11747
The "Forget about this site" feature in the History pane is intended to remove all saved user data that indicates a user has visited a site. This includes removing any HTTP Strict Transport Security (HSTS) settings received from sites that use it. Due to a bug, sites on the pre-load list also have their HSTS setting removed. On the next visit to that site if the user specifies an http: URL rather than secure https: they will not be protected by the pre-loaded HSTS setting. After that visit the site's HSTS setting will be restored. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00011.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00017.html https://bugzilla.mozilla.org/show_bug.cgi?id=1564481 https://www.mozilla.org/security/advisories/mfsa2019-25 https://www.mozilla.org/security/advisories/mfsa2019-26 https://access.redhat.com/security/cve/CVE-2019-11747 https://bugzilla.redhat.com/show_bug.cgi?id=1748664 • CWE-358: Improperly Implemented Security Check for Standard CWE-665: Improper Initialization •
