CVE-2014-1557

La función ConvolveHorizontally en Skia, utilizado en Mozilla Firefox anterior a 31.0, Firefox ESR 24.x anterior a 24.7 y Thunderbird anterior a 24.7, no maneja debidamente el descarte de datos de imágenes durante la ejecución de la función, lo que permite a atacantes remotos ejecutar código arbitrario mediante la provocación del escalado prolongado de imágenes, tal y como fue demostrado mediante el escalado de un imagen de alta calidad.

Christian Holler, David Keeler and Byron Campen discovered multiple memory safety issues in Thunderbird. If a user were tricked in to opening a specially crafted message with scripting enabled, 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 Thunderbird. Atte Kettunen discovered a buffer overflow when interacting with WebAudio buffers. If a user had enabled scripting, an attacker could potentially exploit this to cause a denial of service via application crash or execute arbitrary code with the privileges of the user invoking Thunderbird. Various other issues were also addressed.
