Descriptions

The vmnc decoder in the gstreamer does not initialize the render canvas, which allows remote attackers to obtain sensitive information as demonstrated by thumbnailing a simple 1 frame vmnc movie that does not draw to the allocated render canvas.

El decodificador vmnc en el gstreamer no inicializa el lienzo de renderizado, lo que permite a permite a atacantes remotos obtener información sensible como se demuestra mediante la miniatura de una simple película vmnc de un frame que no dibuja el lienzo de renderizado asignado.

GStreamer is a streaming media framework based on graphs of filters which operate on media data. The following packages have been upgraded to a later upstream version: clutter-gst2, gnome-video-effects, gstreamer1, gstreamer1-plugins-bad-free, gstreamer1-plugins-base, gstreamer1-plugins-good, orc. Security Fix: Multiple flaws were found in gstreamer1, gstreamer1-plugins-base, gstreamer1-plugins-good, and gstreamer1-plugins-bad-free packages. An attacker could potentially use these flaws to crash applications which use the GStreamer framework.
