      jv_parse.c which triggers a heap-based buffer overflow.

  <impact type="normal">
    <p>A remote attacker could trick a victim into processing a specially
      crafted JSON file, possibly resulting in the execution of arbitrary code
      with the privileges of the process.  Additionally, a remote attacker
      could cause a Denial of Service condition.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All jq users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-misc/jq-1.5-r2"
    </code>
