Descriptions

Mozilla Firefox before 33.0 does not properly initialize memory for GIF images, which allows remote attackers to obtain sensitive information from process memory via a crafted web page that triggers a sequence of rendering operations for truncated GIF data within a CANVAS element.

Mozilla Firefox anterior a 33.0 no inicializa debidamente la memoria para los imágenes GIF, lo que permite a atacantes remotos obtener información sensible de la memoria de procesos a través de una página web manipulada que provoca una secuencia de operaciones de renderización para datos GIF truncados dentro de un elemento CANVAS.

Firefox versions prior to 33 leak bits of uninitialized memory when rendering certain types of truncated images onto canvas tags. Secondly, MSRC case #19611cz is a seemingly similar issue with Internet Explorer apparently using bits of uninitialized stack data when handling JPEG files with an oddball DHT.
