CVSS: 7.8EPSS: 0%CPEs: 15EXPL: 0CVE-2018-12379 – Mozilla: Out-of-bounds write with malicious MAR file
https://notcve.org/view.php?id=CVE-2018-12379
When the Mozilla Updater opens a MAR format file which contains a very long item filename, an out-of-bounds write can be triggered, leading to a potentially exploitable crash. This requires running the Mozilla Updater manually on the local system with the malicious MAR file in order to occur. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1. Cuando Mozilla Updater abre un archivo de formato MAR que contiene un nombre de archivo de ítem muy largo, puede desencadenarse una escritura fuera de límites que conduce a un cierre inesperado potencialmente explotable. Esto requiere la ejecución manual de Mozilla Updater en el sistema local con el archivo MAR malicioso para que ocurra. • http://www.securityfocus.com/bid/105280 http://www.securitytracker.com/id/1041610 https://access.redhat.com/errata/RHSA-2018:2692 https://access.redhat.com/errata/RHSA-2018:2693 https://access.redhat.com/errata/RHSA-2018:3403 https://access.redhat.com/errata/RHSA-2018:3458 https://bugzilla.mozilla.org/show_bug.cgi?id=1473113 https://lists.debian.org/debian-lts-announce/2018/11/msg00011.html https://security.gentoo.org/glsa/201810-01 https://security.gentoo.org/glsa/20181 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2018-12377
A use-after-free vulnerability can occur when refresh driver timers are refreshed in some circumstances during shutdown when the timer is deleted while still in use. This results in a potentially exploitable crash. This vulnerability affects Firefox < 62, Firefox ESR < 60.2, and Thunderbird < 60.2.1. Puede ocurrir una vulnerabilidad de uso de memoria previamente liberada cuando se actualizan los temporizadores de los drivers de actualización en algunas circunstancias durante el apagado cuando el temporizador se elimina si sigue estando en uso.
