    dmcox dmcox discovered a boundary error in the zzip_open_shared_io()
    function from zzip/file.c .
    </p>
  </description>
  <impact type="normal">
    <p>
    A remote attacker could entice a user to run a zziplib function with an
    overly long string as an argument which would trigger the buffer
    overflow and may lead to the execution of arbitrary code.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All zziplib users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/zziplib-0.13.49&quot;</code>
  </resolution>
