Advisory: CVE-2018-14404
Disclosed: October 04, 2018
URL: [sparklemotion/nokogiri#1785

<details>
<summary>Nokogiri gem, via libxml2, is affected by multiple vulnerabilities</summary>
<blockquote>
  <p>Nokogiri 1.8.5 has been released.</p>
<p>This is a security and bugfix release. It addresses two CVEs in upstream<br>
libxml2 rated as "medium" by Red Hat, for which details are below.</p>
<p>If you're using your distro's system libraries, rather than Nokogiri's<br>
vendored libraries, there's no security need to upgrade at this time,<br>
though you may want to check with your distro whether they've patched this<br>
(Canonical has patched Ubuntu packages). Note that these patches are not<br>
yet (as of 2018-10-04) in an upstream release of libxml2.</p>
<p>Full details about the security update are available in Github Issue <a href="https://bounce.depfu.com/github.com/sparklemotion/nokogiri/issues/1785">#1785</a>.<br>

<p>[MRI] Pulled in upstream patches from libxml2 that address CVE-2018-14404<br>
and CVE-2018-14567. Full details are available in <a href="https://bounce.depfu.com/github.com/sparklemotion/nokogiri/issues/1785">#1785</a>. Note that these<br>
patches are not yet (as of 2018-10-04) in an upstream release of libxml2.</p>

<p><a href="https://people.canonical.com/%7Eubuntu-security/cve/2018/CVE-2018-14404.html">https://people.canonical.com/~ubuntu-security/cve/2018/CVE-2018-14404.html</a></p>
<p>Description:</p>
<p>A NULL pointer dereference vulnerability exists in the<br>
xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when<br>
parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR<br>
case. Applications processing untrusted XSL format inputs with the use of<br>
the libxml2 library may be vulnerable to a denial of service attack due<br>
to a crash of the application</p>
<p>Canonical rates this vulnerability as "Priority: Medium"</p>
