This mitigation is only required if vulnerable gstreamer-plugins-bad-free and/or gstreamer1-plugins-bad-free packages are installed.
For RHEL 7,
sudo rm /usr/lib*/gstreamer-1.0/libgstvmnc.so
sudo rm /usr/lib*/gstreamer-0.10/libgstvmnc.so
For RHEL 6,
sudo rm /usr/lib*/gstreamer-0.10/libgstvmnc.so
Please note that this mitigation deletes the vulnerable VMware NC decoder, which removes the functionality to play VMware movie files.
