libvorbis vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 17.10
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS


libvorbis could be made to crash or run programs as your login if it opened a specially crafted file.

Software Description

  • libvorbis - The Vorbis General Audio Compression Codec


Richard Zhu discovered that libvorbis incorrectly handled certain sound files. An attacker could use this to cause libvorbis to crash, resulting in a denial or service, or possibly execute arbitrary code.
