🚨 [security] Update nokogiri: 1.8.4 → 1.8.5 (patch)

[depfu]

⚠️ No CI detected ⚠️

You don't seem to have any Continuous Integration service set up!

Without a service that will test the Depfu branches and pull requests, we can't inform you if incoming updates actually work with your app. We think that this degrades the service we're trying to provide down to a point where it is more or less meaningless.

This is fine if you just want to give Depfu a quick try. If you want to really let Depfu help you keep your app up-to-date, we recommend setting up a CI system:

• Our friends at Travis-CI provide excellent service.
• Circle CI are good, too, and have a free plan that will cover basic needs.
• If you use something like Jenkins, make sure that you're using the Github integration correctly so that it reports status data back to Github.
• If you have already set up a CI for this repository, you might need to check your configuration. Make sure it will run on all new branches. If you don’t want it to run on every branch, you can whitelist branches starting with depfu/.

It might be necessary to once deactivate and reactivate your project in Depfu for the CI service to be properly detected.

🚨 Your version of nokogiri has known security vulnerabilities 🚨

Advisory: CVE-2018-14404
Disclosed: October 04, 2018
URL: https://github.com/sparklemotion/nokogiri/issues/1785

Nokogiri gem, via libxml2, is affected by multiple vulnerabilities

Nokogiri 1.8.5 has been released.

This is a security and bugfix release. It addresses two CVEs in upstream
libxml2 rated as "medium" by Red Hat, for which details are below.

If you're using your distro's system libraries, rather than Nokogiri's
vendored libraries, there's no security need to upgrade at this time,
though you may want to check with your distro whether they've patched this
(Canonical has patched Ubuntu packages). Note that these patches are not
yet (as of 2018-10-04) in an upstream release of libxml2.

Full details about the security update are available in Github Issue #1785.
[#1785]: #1785

[MRI] Pulled in upstream patches from libxml2 that address CVE-2018-14404
and CVE-2018-14567. Full details are available in #1785. Note that these
patches are not yet (as of 2018-10-04) in an upstream release of libxml2.

CVE-2018-14404

Permalink:

https://people.canonical.com/~ubuntu-security/cve/2018/CVE-2018-14404.html

Description:

A NULL pointer dereference vulnerability exists in the
xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when
parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR
case. Applications processing untrusted XSL format inputs with the use of
the libxml2 library may be vulnerable to a denial of service attack due
to a crash of the application

Canonical rates this vulnerability as "Priority: Medium"
