https://notcve.org/view.php?id=CVE-2019-9810
Incorrect alias information in IonMonkey JIT compiler for Array.prototype.slice method may lead to missing bounds check and a buffer overflow. This vulnerability affects Firefox < 66.0.1, Firefox ESR < 60.6.1, and Thunderbird < 60.6.1. La información incorrecta de alias en el compilador IonMonkey JIT para el método Array.prototype.slice puede llevar a la falta de comprobación de límites y a un desbordamiento del búfer. Esta vulnerabilidad afecta a Firefox versiones anteriores a 66.0.1, Firefox ESR versiones anteriores a 60.6.1 y Thunderbird versiones anteriores a 60.6.1. This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. • https://www.exploit-db.com/exploits/46605 https://www.exploit-db.com/exploits/47752 https://github.com/0vercl0k/CVE-2019-9810 https://github.com/xuechiyaobai/CVE-2019-9810-PoC http://packetstormsecurity.com/files/155592/Mozilla-Firefox-Windows-64-Bit-Chain-Exploit.html https://access.redhat.com/errata/RHSA-2019:0966 https://access.redhat.com/errata/RHSA-2019:1144 https://bugzilla.mozilla.org/show_bug.cgi?id=1537924 https://www.mozilla.org/security/advisories/mfsa2019-09 https:/ • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

The Upgrade-Insecure-Requests (UIR) specification states that if UIR is enabled through Content Security Policy (CSP), navigation to a same-origin URL must be upgraded to HTTPS. Firefox will incorrectly navigate to an HTTP URL rather than perform the security upgrade requested by the CSP in some circumstances, allowing for potential man-in-the-middle attacks on the linked resources. This vulnerability affects Firefox < 66. La especificación de Upgrade-Insecure-Requests (UIR) establece que si la UIR se habilita mediante Content Security Policy (CSP), la navegación a una URL del mismo origen debe actualizarse a HTTPS. Firefox navegará incorrectamente a una URL HTTP en lugar de realizar la actualización de seguridad solicitada por el CSP en algunas circunstancias, lo que permite posibles ataques de intermediarios en los recursos vinculados. • https://bugzilla.mozilla.org/show_bug.cgi?id=1437009 https://bugzilla.mozilla.org/show_bug.cgi?id=1515863 https://w3c.github.io/webappsec-upgrade-insecure-requests https://www.mozilla.org/security/advisories/mfsa2019-07 • CWE-346: Origin Validation Error •

https://notcve.org/view.php?id=CVE-2019-9797
Cross-origin images can be read in violation of the same-origin policy by exporting an image after using createImageBitmap to read the image and then rendering the resulting bitmap image within a canvas element. This vulnerability affects Firefox < 66. Las imágenes de origen cruzado se pueden leer infringiendo la política del mismo origen al exportar una imagen después de utilizar createImageBitmap para leer la imagen y luego renderizar la imagen de mapa de bits resultante dentro de un elemento canvas.
