FFmpeg is a complete solution to record, convert and stream audio and video. gst-plugins-ffmpeg is a FFmpeg based gstreamer plugin which includes a vulnerable copy of FFmpeg code. Mplayer is a multimedia player which also includes a vulnerable copy of the code.
Multiple vulnerabilities were found in FFmpeg:
A remote attacker could entice a user to open a specially crafted media file, possibly leading to the execution of arbitrary code with the privileges of the user running the application, or a Denial of Service.
There is no known workaround at this time.
