https://notcve.org/view.php?id=CVE-2018-18500
A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements. This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65. Una vulnerabilidad de memoria previamente liberada puede ocurrir a la hora de analizar una transmisión HTML5 junto con elementos HTML personalizados. Esto resulta en la liberación del objeto de análisis de transmisión mientras está en uso, conduciendo potencialmente a un cierre inesperado explotable. • https://github.com/sophoslabs/CVE-2018-18500 http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00021.html http://www.securityfocus.com/bid/106781 https://access.redhat.com/errata/RHSA-2019:0218 https://access.redhat.com/errata/RHSA-2019:0219 https://access.redhat.com/errata/RHSA-2019:0269 https://access.redhat.com/errata/RHSA-2019:0270 https://lists.debian.org/debian-lts-announce/2019/01/msg00025.html https://lists.debian.org/debian-lts-announce/2019/02/msg00024 • CWE-416: Use After Free •
CVSS: 10.0EPSS: 0%CPEs: 18EXPL: 0CVE-2018-18505 – Mozilla: Privilege escalation through IPC channel messages
https://notcve.org/view.php?id=CVE-2018-18505
An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65. Una solución anterior para la vulnerabilidad de comunicación entre procesos (IPC), CVE-2011-3079, añadía una autenticación para comunicaciones entre endpoints de IPC y servidores padres durante la creación de procesos IPC. • http://lists.opensuse.org/opensuse-security-announce/2019-07/msg00021.html http://www.securityfocus.com/bid/106781 https://access.redhat.com/errata/RHSA-2019:0218 https://access.redhat.com/errata/RHSA-2019:0219 https://access.redhat.com/errata/RHSA-2019:0269 https://access.redhat.com/errata/RHSA-2019:0270 https://bugzilla.mozilla.org/show_bug.cgi?id=1087565 https://lists.debian.org/debian-lts-announce/2019/01/msg00025.html https://lists.debian.org/debian-lts-announce/2019/02&# • CWE-287: Improper Authentication •

https://notcve.org/view.php?id=CVE-2018-18493
A buffer overflow can occur in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. Puede ocurrir un desbordamiento de búfer en la librería SKIA durante los cálculos de un desplazamiento de búfer con acciones de hardware aceleradas de CANVAS 2D, debido al uso de cálculos de 32-bit en vez de 64-bit.

Limitations on the URIs allowed to WebExtensions by the browser.windows.create API can be bypassed when a pipe in the URL field is used within the extension to load multiple pages as a single argument. This could allow a malicious WebExtension to open privileged about: or file: locations. This vulnerability affects Firefox < 64.
