<impact type="high">
<p>
A remote attacker could exploit this vulnerability to execute arbitrary
code by sending a specially crafted HTTP message to the client. NOTE:
Successful exploitation requires a man in the middle attack, a DNS
spoofing attack or a compromise of no-ip.com servers.

</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>

<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-dns/noip-updater-2.1.9&quot;</code>
