Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 48.0 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Multiples vulnerabilidades no especificadas en el motor del navegador en Mozilla Firefox en versiones anteriores a 48.0 permite a atacantes remotos provocar una denegación de servicio (corrupción de memoria y caída de aplicación) o posiblemente ejecutar código arbitrario a través de vectores desconocidos.
Gustavo Grieco discovered an out-of-bounds read during XML parsing in some circumstances. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via application crash, or obtain sensitive information. Toni Huttunen discovered that once a favicon is requested from a site, the remote server can keep the network connection open even after the page is closed. A remote attacker could potentially exploit this to track users, resulting in information disclosure. Various other issues were also addressed.
