    <p>
    Video Disk Recorder (VDR) is a Linux-based digital video recorder.
    The VDR program handles the On Screen Menu system that offers complete
    control over channel settings, timers and recordings.

  <description>
    <p>
    Javier Fernandez-Sanguino Pena from the Debian Security Audit Team
    discovered that VDR accesses user-controlled files insecurely.
    </p>
  </description>
  <impact type="normal">
    <p>
    A local attacker could create malicious links and invoke a VDR
    recording that would overwrite arbitrary files on the system.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All VDR users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=media-video/vdr-1.2.6-r1&quot;</code>
  </resolution>
