Welcome to Depfu 👋

This is one of the first three pull requests with dependency updates we've sent your way. We tried to start with a few easy patch-level updates. Hopefully your tests will pass and you can merge this pull request without too much risk. This should give you an idea how Depfu works in general.

After you merge your first pull request, we'll send you a few more. We'll never open more than seven PRs at the same time so you're not getting overwhelmed with updates.

Let us know if you have any questions. Thanks so much for giving Depfu a try!

🚨 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.
