[Security] Bump nokogiri from 1.10.1 to 1.11.2 in /backend

[dependabot-preview[bot]]

Bumps nokogiri from 1.10.1 to 1.11.2. 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

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.

Release notes

Sourced from nokogiri's releases.

1.11.2 / 2021-03-11

Fixed

• [CRuby] NodeSet may now safely contain Node objects from multiple documents. Previously the GC lifecycle of the parent Document objects could lead to nodes being GCed while still in scope. [#1952]
• [CRuby] Patch libxml2 to avoid "huge input lookup" errors on large CDATA elements. (See upstream GNOME/libxml2#200 and GNOME/libxml2!100.) [#2132].
• [CRuby+Windows] Enable Nokogumbo (and other downstream gems) to compile and link against nokogiri.so by including LDFLAGS in Nokogiri::VERSION_INFO. [#2167]
• [CRuby] {XML,HTML}::Document.parse now invokes #initialize exactly once. Previously #initialize was invoked twice on each object.
• [JRuby] {XML,HTML}::Document.parse now invokes #initialize exactly once. Previously #initialize was not called, which was a problem for subclassing such as done by Loofah.

Improved

• Reduce the number of object allocations needed when parsing an HTML::DocumentFragment. [#2087] (Thanks, @ashmaroli!)
• [JRuby] Update the algorithm used to calculate Node#line to be wrong less-often. The underlying parser, Xerces, does not track line numbers, and so we've always used a hacky solution for this method. [#1223, #2177]
• Introduce --enable-system-libraries and --disable-system-libraries flags to extconf.rb. These flags provide the same functionality as --use-system-libraries and the NOKOGIRI_USE_SYSTEM_LIBRARIES environment variable, but are more idiomatic. [#2193] (Thanks, @eregon!)
• [TruffleRuby] --disable-static is now the default on TruffleRuby when the packaged libraries are used. This is more flexible and compiles faster. (Note, though, that the default on TR is still to use system libraries.) [#2191, #2193] (Thanks, @eregon!)

Changed

• Nokogiri::XML::Path is now a Module (previously it has been a Class). It has been acting solely as a Module since v1.0.0. See 8461c74.

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]

1.11.0 / 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.
