Multiple flaws were discovered in GStreamer's FLC/FLI/FLX media file format decoding plug-in. A remote attacker could use these flaws to cause an application using GStreamer to crash or, potentially, execute arbitrary code with the privileges of the user running the application.
This mitigation is only required if vulnerable gstreamer-plugins-good and/or gstreamer1-plugins-good packages are installed.
For RHEL 7,
sudo rm /usr/lib/gstreamer-1.0/libgstflxdec.so
sudo rm /usr/lib/gstreamer-0.10/libgstflxdec.so
For RHEL 5 and RHEL 6,
sudo rm /usr/lib*/gstreamer-0.10/libgstflxdec.so
Please note that this mitigation deletes the vulnerable FLI/FLC/FLX animation demuxer file(s), which removes the functionality to play FLI/FLC/FLX animation files.
