  <impact type="normal">
    <p>A remote user could craft a specifically crafted image file that could
      execute arbitrary code or cause denial of service.
    </p>
  </impact>
  <workaround>
    <p>The user should refrain from opening files from untrusted third parties
      or accessing untrusted remote sites (or disable the VLC browser plugins),
      until they upgrade.
    </p>
  </workaround>
  <resolution>
    <p>All VLC users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=media-video/vlc-3.0.10"
    </code>
