Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/gstreamer1-plugins-bad-free.
  2. 2Review the reported fix. Source-reported workaround: Applications that do not require JPEG 2000 decimation can avoid using the jp2kdecimator element and reject untrusted JPEG 2000 media before it reaches a pipeline that uses this element.
