Mozilla developers and community members reported memory safety bugs present in Firefox 64. 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 < 65. Los desarrolladores de Mozilla y los miembros de la comunidad reportaron problemas de seguridad existentes en Firefox 64. Algunos de estos errores mostraron evidencias de corrupción de memoria y se cree que, con el esfuerzo necesario, se podrían explotar para ejecutar código arbitrario. • http://www.securityfocus.com/bid/106773 https://usn.ubuntu.com/3874-1 https://www.mozilla.org/security/advisories/mfsa2019-01 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

A crash and out-of-bounds read can occur when the buffer of a texture client is freed while it is still in use during graphic operations. This results is a potentially exploitable crash and the possibility of reading from the memory of the freed buffers. This vulnerability affects Firefox < 65. Un cierre inesperado y una lectura fuera de límites podrían ocurrir cuando el búfer de la textura de un cliente se libera mientras está en uso durante las operaciones gráficas. Esto resulta en un cierre potencialmente explotable y la posibilidad de leer desde la memoria de los búferes liberados. • http://www.securityfocus.com/bid/106773 https://usn.ubuntu.com/3874-1 https://www.mozilla.org/security/advisories/mfsa2019-01 • CWE-125: Out-of-bounds Read •
CVSS: 6.1EPSS: 0%CPEs: 29EXPL: 0CVE-2018-18506 – Mozilla: Proxy Auto-Configuration file can define localhost access to be proxied
https://notcve.org/view.php?id=CVE-2018-18506
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65. Cuando la autodetección del proxy está habilitada, si un servidor web proporciona un archivo de autoconfiguración de proxy (PAC) o si dicho archivo se carga localmente, este último puede especificar peticiones al host local que están destinadas a enviarse a través del proxy hacia otro servidor. Este comportamiento está prohibido por defecto cuando un proxy se configura manualmente. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00043.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00023.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00043.html http://www.securityfocus.com/bid/106773 https://access.redhat.com/errata/RHSA-2019:0622 https://access.redhat.com/errata/RHSA-2019:0623 https://access.redhat.com/errata/RHSA-2019:0680 https:/ • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVSS: 9.8EPSS: 22%CPEs: 18EXPL: 1CVE-2018-18500 – Mozilla: Use-after-free parsing HTML5 stream
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 •
