Synopsis

Multiple vulnerabilities have been found in FFmpeg, the worst of which allows remote attackers to execute arbitrary code.

Background

FFmpeg is a complete, cross-platform solution to record, convert and stream audio and video.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=media-video/ffmpeg-3.2.4"
