[Security] Bump nokogiri from 1.8.5 to 1.11.1

[dependabot-preview]

Bumps nokogiri from 1.8.5 to 1.11.1. 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.

CVE-2019-13117

https://people.canonical.com/~ubuntu-security/cve/2019/CVE-2019-13117.html

Patched versions: >= 1.10.5 Unaffected versions: none

Sourced from The GitHub Security Advisory Database.

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

Sourced from The Ruby Advisory Database.

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.

Patched versions: >= 1.10.8 Unaffected versions: none

Sourced from The GitHub Security Advisory Database.

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

Mitigation

Affected versions: <= 1.10.10

Sourced from The Ruby Advisory Database.

Nokogiri gem, via libxslt, is affected by improper access control vulnerability Nokogiri v1.10.3 has been released.

This is a security release. It addresses a CVE in upstream libxslt rated as "Priority: medium" by Canonical, and "NVD Severity: high" by Debian. More details are available 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 this patch is not yet (as of 2019-04-22) in an upstream release of libxslt.

Full details about the security update are available in Github Issue [#1892] sparklemotion/nokogiri#1892.

Patched versions: >= 1.10.3 Unaffected versions: none

Release notes

Sourced from nokogiri's releases.

v1.11.1 / 2021-01-06

Fixed

• [CRuby] If libxml-ruby is loaded before nokogiri, the SAX and Push parsers no longer call libxml-ruby's handlers. Instead, they defensively override the libxml2 global handler before parsing. [#2168]

v1.11.0 / 2021-01-03

Notes

Faster, more reliable installation: Native Gems for Linux and OSX/Darwin

"Native gems" contain pre-compiled libraries for a specific machine architecture. On supported platforms, this removes the need for compiling the C extension and the packaged libraries. This results in much faster installation and more reliable installation, which as you probably know are the biggest headaches for Nokogiri users.

We've been shipping native Windows gems since 2009, but starting in v1.11.0 we are also shipping native gems for these platforms:

• Linux: x86-linux and x86_64-linux -- including musl platforms like alpine
• OSX/Darwin: x86_64-darwin and arm64-darwin

We'd appreciate your thoughts and feedback on this work at #2075.

Dependencies

Ruby

This release introduces support for Ruby 2.7 and 3.0 in the precompiled native gems.

This release ends support for:

• Ruby 2.3, for which official support ended on 2019-03-31 [#1886] (Thanks @ashmaroli!)
• Ruby 2.4, for which official support ended on 2020-04-05
• JRuby 9.1, which is the Ruby 2.3-compatible release.
