Mitigation
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.
