<impact type="normal">
<p>
A remote attacker could entice a user to open a specially crafted XML
document with an application using libxml2, possibly resulting in a
high CPU consumption. Note that this vulnerability could also be
triggered without user interaction by an automated system processing
XML content.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libxml2 users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libxml2-2.6.30-r1&quot;</code>
</resolution>
