Race condition in the get implementation in the ServiceWorkerManager class in the Service Worker subsystem in Mozilla Firefox before 46.0 allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow and application crash) via a crafted web site.
Condición de carrera en la implementación de get en la clase ServiceWorkerManager en el subsistema Service Worker en Mozilla Firefox en versiones anteriores a 46.0 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (desbordamiento de buffer y caída de aplicación) a través de un sitio web manipulado.
Christian Holler, Tyson Smith, Phil Ringalda, Gary Kwong, Jesse Ruderman, Mats Palmgren, Carsten Book, Boris Zbarsky, David Bolter, Randell Jesup, Andrew McCreight, and Steve Fink discovered multiple memory safety issues in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service via application crash, or execute arbitrary code with the privileges of the user invoking Firefox. Various other issues were also addressed.
