[Security] Bump nokogiri from 1.9.1 to 1.11.7

[dependabot-preview]

Bumps nokogiri from 1.9.1 to 1.11.7. This update includes security fixes.

Vulnerabilities fixed

Sourced from The Ruby Advisory Database.

Nokogiri Command Injection Vulnerability 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.

Upgrade to Nokogiri v1.10.4, or avoid calling the undocumented method Nokogiri::CSS::Tokenizer#load_file with untrusted user input.

Patched versions: >= 1.10.4 Unaffected versions: none

Nokogiri gem, via libxslt, is affected by multiple vulnerabilities Nokogiri v1.10.5 has been released.

This is a security release. It addresses three CVEs in upstream libxml2, 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 libxslt 1.1.34 addresses these vulnerabilities.

Full details about the security update are available in Github Issue [#1943] sparklemotion/nokogiri#1943.

Moderate severity vulnerability that affects nokogiri xmlStringLenDecodeEntities in parser.c in libxml2 2.9.10 has an infinite loop in a certain end-of-file situation. The Nokogiri RubyGem has patched it's vendored copy of libxml2 in order to prevent this issue from affecting nokogiri.

Affected versions: < 1.10.8

libxml2 2.9.10 has an infinite loop in a certain end-of-file situation Nokogiri has backported the patch for CVE-2020-7595 into its vendored version of libxml2, and released this as v1.10.8

CVE-2020-7595 has not yet been addressed in an upstream libxml2 release, and so Nokogiri versions <= v1.10.7 are vulnerable.

XXE in Nokogiri

Severity

Nokogiri maintainers have evaluated this as Low Severity (CVSS3 2.6).

Description

In Nokogiri versions <= 1.11.0.rc3, XML Schemas parsed by Nokogiri::XML::Schema are trusted by default, allowing external resources to be accessed over the network, potentially enabling XXE or SSRF attacks.

This behavior is counter to the security policy followed by Nokogiri maintainers, which is to treat all input as untrusted by default whenever possible.

Please note that this security fix was pushed into a new minor version, 1.11.x, rather than a patch release to the 1.10.x branch, because it is a breaking change for some schemas and the risk was assessed to be "Low Severity".

Affected Versions

Nokogiri <= 1.10.10 as well as prereleases 1.11.0.rc1, 1.11.0.rc2, and 1.11.0.rc3

Update packaged dependency libxml2 from 2.9.10 to 2.9.12

Summary

Nokogiri v1.11.4 updates the vendored libxml2 from v2.9.10 to v2.9.12 which addresses:

• CVE-2019-20388 (Medium severity)
• CVE-2020-24977 (Medium severity)
• CVE-2021-3517 (Medium severity)
• CVE-2021-3518 (Medium severity)
• CVE-2021-3537 (Low severity)
• CVE-2021-3541 (Low severity)

Note that two additional CVEs were addressed upstream but are not relevant to this release. CVE-2021-3516 via xmllint is not present in Nokogiri, and CVE-2020-7595 has been patched in Nokogiri since v1.10.8 (see #1992).

Please note that this advisory only applies to the CRuby implementation of Nokogiri < 1.11.4, and only if the packaged version of libxml2 is being used. If you've overridden defaults at installation time to use system libraries instead of packaged libraries, you should instead pay attention to your distro's libxml2 release announcements.

Mitigation

Upgrade to Nokogiri >= 1.11.4.
