Comment (by cypherpunks):

 > Security researcher Aki Helin reported a use-after-free when playing
 certain MP3 format audio files on the web using the Fluendo MP3 plugin for
 GStreamer on Linux. This is due to a flaw in handling certain MP3 files by
 the plugin and its interaction with Mozilla code. This can lead to a
 potentially exploitable crash.
