<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2016-4658">CVE-2016-4658</a>
<p>Namespace nodes must be copied to avoid use-after-free errors.
But they don't necessarily have a physical representation in a
document, so simply disallow them in XPointer ranges.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2016-5131">CVE-2016-5131</a>
<p>The old code would invoke the broken xmlXPtrRangeToFunction.
range-to isn't really a function but a special kind of
location step. Remove this function and always handle range-to
in the XPath code.
The old xmlXPtrRangeToFunction could also be abused to trigger
a use-after-free error with the potential for remote code
execution.</p></li>
</ul>
<p>For Debian 7 <q>Wheezy</q>, these problems have been fixed in version
2.8.0+dfsg1-7+wheezy7.</p>
<p>We recommend that you upgrade your libxml2 packages.</p>

these updates to your system and frequently asked questions can be
