Nokogiri Changelog

1.10.9 / 2020-03-01

Fixed

  • [MRI] Raise an exception when Nokogiri detects a specific libxml2 edge case involving blank Schema nodes wrapped by Ruby objects that would cause a segfault. Currently no fix is available upstream, so we're preventing a dangerous operation and informing users to code around it if possible. [#1985, #2001]
  • [JRuby] Change NodeSet#to_a to return a RubyArray instead of Object, for compilation under JRuby 9.2.9 and later. [#1968, #1969] (Thanks, @headius!)

1.10.8 / 2020-02-10

Security

[MRI] Pulled in upstream patch from libxml that addresses CVE-2020-7595. Full details are available in #1992. Note that this patch is not yet (as of 2020-02-10) in an upstream release of libxml.

1.10.7 / 2019-12-03

Bug

  • [MRI] Ensure the patch applied in v1.10.6 works with GNU patch. [#1954]

1.10.6 / 2019-12-03

Bug

  • [MRI] Fix FreeBSD installation of vendored libxml2. [#1941, #1953] (Thanks, @nurse!)

1.10.5 / 2019-10-31

Security

[MRI] Vendored libxslt upgraded to v1.1.34 which addresses three CVEs for libxslt:

  • CVE-2019-13117
  • CVE-2019-13118
  • CVE-2019-18197
  • CVE-2019-19956

More details are available at #1943.

Dependencies

  • [MRI] vendored libxml2 is updated from 2.9.9 to 2.9.10
  • [MRI] vendored libxslt is updated from 1.1.33 to 1.1.34

1.10.4 / 2019-08-11

Security

Address CVE-2019-5477 (#1915)

A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess by Ruby's Kernel.open method. Processes are vulnerable only if the undocumented method Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.

This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.

This CVE's public notice is #1915

1.10.3 / 2019-04-22

Security Notes

[MRI] Pulled in upstream patch from libxslt that addresses CVE-2019-11068. Full details are available in #1892. Note that this patch is not yet (as of 2019-04-22) in an upstream release of libxslt.

Bug fixes

  • Fix a bug introduced in v1.9.0 where XML::DocumentFragment#dup no longer returned an instance of the callee's class, instead always returning an XML::DocumentFragment.

  • [MRI] Improve installation experience on macOS High Sierra (Darwin). [#1812, #1813] (Thanks, @gpakosz and @nurse!)
  • [MRI] Node#dup supports copying a node directly to a new document. See the method documentation for details.

Bug fixes

  • [MRI] Fix regression in installation when building against system libraries, where some systems would not be able to find libxml2 or libxslt when present. (Regression introduced in v1.8.3.) [#1722]
  • [JRuby] Fix node reparenting when the destination doc is empty. [#1773]

1.8.4 / 2018-07-03

Bug fixes

  • [MRI] Fix memory leak when creating nodes with namespaces. (Introduced in v1.5.7) [#1771]

1.8.3 / 2018-06-16

Security Notes

[MRI] Behavior in libxml2 has been reverted which caused CVE-2018-8048 (loofah gem), CVE-2018-3740 (sanitize gem), and CVE-2018-3741 (rails-html-sanitizer gem). The commit in question is here:

https://github.com/GNOME/libxml2/commit/960f0e2

and more information is available about this commit and its impact here:

flavorjones/loofah#144

This release simply reverts the libxml2 commit in question to protect users of Nokogiri's vendored libraries from similar vulnerabilities.

If you're offended by what happened here, I'd kindly ask that you comment on the upstream bug report here:

1.6.8.1 / 2016-10-03

Dependency License Notes

Removes required dependency on the pkg-config gem. This dependency was introduced in v1.6.8 and, because it's distributed under LGPL, was objectionable to many Nokogiri users (#1488, #1496).

This version makes pkg-config an optional dependency. If it's installed, it's used; but otherwise Nokogiri will attempt to work around its absence.

1.6.8 / 2016-06-06

Security Notes

[MRI] Bundled libxml2 is upgraded to 2.9.4, which fixes many security issues. Many of these had previously been patched in the vendored libxml 2.9.2 in the 1.6.7.x branch, but some are newer.

See these libxml2 email posts for more:

For a more detailed analysis, you may care to read Canonical's take on these security issues:

[MRI] Bundled libxslt is upgraded to 1.1.29, which fixes a security issue as well as many long-known outstanding bugs, some features, some portability improvements, and general cleanup.

See this libxslt email post for more:

1.6.2 / 2014-05-12

Security Note

A set of security and bugfix patches have been backported from the libxml2 and libxslt repositories onto the version of 2.8.0 packaged with Nokogiri, including these notable security fixes:

It is recommended that you upgrade from 1.6.x to this version as soon as possible.

Compatibility Note

Now requires libxml >= 2.6.21 (was previously >= 2.6.17).

Features
