  <background>
    <p>TestDisk is powerful free data recovery software! It was primarily
      designed to help recover lost partitions and/or make non-booting disks
      bootable again when these symptoms are caused by faulty software: certain
      types of viruses or human error (such as accidentally deleting a
      Partition Table). Partition table recovery using TestDisk is really easy.
    </p>
  </background>
  <description>
    <p>A buffer overflow can be triggered within TestDisk when a malicious disk
      image is attempting to be recovered.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could coerce the victim to run TestDisk against their
      malicious image.  This may be leveraged by an attacker to crash TestDisk
      and gain control of program execution.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All TestDisk users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-admin/testdisk-7.0-r2"
    </code>
