The gstreamer-plugins packages contain plug-ins used by the GStreamer streaming-media framework to support a wide variety of media formats. An integer overflow flaw, leading to a heap-based buffer overflow, and a stack-based buffer overflow flaw were found in various ModPlug music file format library modules, embedded in GStreamer. An attacker could create specially-crafted music files that, when played by a victim, would cause applications using GStreamer to crash or, potentially, execute arbitrary code. All users of gstreamer-plugins are advised to upgrade to these updated packages, which contain backported patches to correct these issues. After installing the update, all applications using GStreamer must be restarted for the changes to take effect.
