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 •
CVSS: 9.8EPSS: 1%CPEs: 18EXPL: 0CVE-2018-18493 – Mozilla: Buffer overflow in accelerated 2D canvas with Skia
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. Esto resulta en un cierre inesperado potencialmente explotable. • http://www.securityfocus.com/bid/106168 https://access.redhat.com/errata/RHSA-2018:3831 https://access.redhat.com/errata/RHSA-2018:3833 https://access.redhat.com/errata/RHSA-2019:0159 https://access.redhat.com/errata/RHSA-2019:0160 https://bugzilla.mozilla.org/show_bug.cgi?id=1504452 https://lists.debian.org/debian-lts-announce/2018/12/msg00002.html https://security.gentoo.org/glsa/201903-04 https://usn.ubuntu.com/3844-1 https://usn.ubuntu.com/3868-1 https:/&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •

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. La API browser.windows.create permitía que las WebExtensions omitiesen las limitaciones en las URI cuando una tubería (pipe) en el campo URL se utiliza con la extensión para cargar múltiples páginas como un solo argumento.

https://notcve.org/view.php?id=CVE-2018-18498
A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This leads to a possible out-of-bounds write. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64. Puede ocurrir una vulnerabilidad potencial que conduce a un desbordamiento de enteros durante los cálculos de tamaño de búfer cuando se emplea un valor bruto en vez del valor comprobado.
