CVSS: 6.1EPSS: 0%CPEs: 4EXPL: 0CVE-2019-11762 – Mozilla: document.domain-based origin isolation has same-origin-property violation
https://notcve.org/view.php?id=CVE-2019-11762
If two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Si dos documentos del mismo origen configuran a document.domain de manera diferente para convertirse en origen cruzado, es posible llamar arbitrariamente a DOM methods/getters/setters en la ventana ahora de origen cruzado. Esta vulnerabilidad afecta a Firefox versiones anteriores a la versión 70, Thunderbird versiones anteriores a la versión 68.2 y Firefox ESR versiones anteriores a la versión 68.2. A flaw was found in Mozilla's firefox and thunderbird where if two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window. • https://bugzilla.mozilla.org/show_bug.cgi?id=1582857 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2019-33 https://www.mozilla.org/security/advisories/mfsa2019-34 https://www.mozilla.org/security/advisories/mfsa2019-35 https://access.redhat.com/security/cve/CVE-2019-11762 https://bugzilla.redhat.com/show_bug.cgi?id=1764443 • CWE-346: Origin Validation Error CWE-829: Inclusion of Functionality from Untrusted Control Sphere •
CVSS: 8.8EPSS: 1%CPEs: 4EXPL: 1CVE-2019-11764 – Mozilla: Memory safety bugs fixed in Firefox 70 and Firefox ESR 68.2
https://notcve.org/view.php?id=CVE-2019-11764
Mozilla developers and community members reported memory safety bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron bugs de seguridad de memoria presentes en Firefox versión 69 y Firefox ESR versión 68.1. Algunos de estos errores mostraron evidencia de corrupción de memoria y suponemos que con un esfuerzo suficiente algunos de estos podrían ser explotados para ejecutar código arbitrario. • https://bugzilla.mozilla.org/buglist.cgi?bug_id=1558522%2C1577061%2C1548044%2C1571223%2C1573048%2C1578933%2C1575217%2C1583684%2C1586845%2C1581950%2C1583463%2C1586599 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2019-33 https://www.mozilla.org/security/advisories/mfsa2019-34 https://www.mozilla.org/security/advisories/mfsa2019-35 https://access.redhat.com/security/cve/CVE-2019-11764 https://bugzilla.redhat.com/show_bug.cgi?id=17 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 1%CPEs: 4EXPL: 0CVE-2019-11759 – Mozilla: Stack buffer overflow in HKDF output
https://notcve.org/view.php?id=CVE-2019-11759
An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the stack. This could be used by an attacker to execute arbitrary code or more likely lead to a crash. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Un atacante podría haber causado que 4 bytes de salida HMAC se escribieran más allá del final de un búfer almacenado en la pila. Esto podría ser usado por un atacante para ejecutar código arbitrario o, más probablemente, conllevar a un bloqueo. • https://bugzilla.mozilla.org/show_bug.cgi?id=1577953 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2019-33 https://www.mozilla.org/security/advisories/mfsa2019-34 https://www.mozilla.org/security/advisories/mfsa2019-35 https://access.redhat.com/security/cve/CVE-2019-11759 https://bugzilla.redhat.com/show_bug.cgi?id=1764440 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

https://notcve.org/view.php?id=CVE-2019-11760
A fixed-size stack buffer could overflow in nrappkit when doing WebRTC signaling. This resulted in a potentially exploitable crash in some instances. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Un búfer de pila de tamaño fijo podría desbordarse en nrappkit cuando realiza la señalización de WebRTC.

By using a form with a data URI it was possible to gain access to the privileged JSONView object that had been cloned into content. Impact from exposing this object appears to be minimal, however it was a bypass of existing defense in depth mechanisms. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. Mediante el uso de un formulario con un URI de datos, fue posible conseguir acceso al objeto JSONView privilegiado que había sido clonado en contenido. El impacto de exponer este objeto parece ser mínimo, sin embargo, fue una omisión de los mecanismos de defensa existentes en profundidad. • https://bugzilla.mozilla.org/show_bug.cgi?id=1561502 https://security.gentoo.org/glsa/202003-10 https://usn.ubuntu.com/4335-1 https://www.mozilla.org/security/advisories/mfsa2019-33 https://www.mozilla.org/security/advisories/mfsa2019-34 https://www.mozilla.org/security/advisories/mfsa2019-35 https://access.redhat.com/security/cve/CVE-2019-11761 https://bugzilla.redhat.com/show_bug.cgi?id=1764442 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-749: Exposed Dangerous Method or Function CWE-862: Missing Authorization •
