    GNU cpio has been discovered.

  <impact type="normal">
    <p>
    A remote attacker could entice a user to open a specially crafted
    archive file resulting in a stack-based buffer overflow, possibly
    crashing the application. It is disputed whether the execution of
    arbitrary code is possible.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All GNU cpio users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-arch/cpio-2.9-r1&quot;</code>
  </resolution>
