The gstreamer-plugins package contains plugins used by the GStreamer streaming-media framework to support a wide variety of media types. A heap buffer overflow was found in the GStreamer"s QuickTime media file format decoding plug-in. An attacker could create a carefully-crafted QuickTime media .mov file that would cause an application using GStreamer to crash or, potentially, execute arbitrary code if played by a victim. All users of gstreamer-plugins are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. After installing the update, all applications using GStreamer must be restarted for the changes to take effect.
