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.

Common Vulnerability Scoring System (CVSS) Score Details

Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
