Nokogiri gem, via libxml, is affected by DoS and RCE vulnerabilities The version of libxml2 packaged with Nokogiri contains several vulnerabilities. Nokogiri has mitigated these issues by upgrading to libxml 2.9.5.

It was discovered that a type confusion error existed in libxml2. An attacker could use this to specially construct XML data that could cause a denial of service or possibly execute arbitrary code. (CVE-2017-0663)

It was discovered that libxml2 did not properly validate parsed entity references. An attacker could use this to specially construct XML data that could expose sensitive information. (CVE-2017-7375)

It was discovered that a buffer overflow existed in libxml2 when handling HTTP redirects. An attacker could use this to specially construct XML data that could cause a denial of service or possibly execute arbitrary code. (CVE-2017-7376)

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.

Nokogiri gem contains several vulnerabilities in libxml2 and libxslt Nokogiri version 1.7.1 has been released, pulling in several upstream patches to the vendored libxml2 to address the following CVEs:

CVE-2016-4658 CVSS v3 Base Score: 9.8 (Critical) libxml2 in Apple iOS before 10, OS X before 10.12, tvOS before 10, and watchOS before 3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.

CVE-2016-5131 CVSS v3 Base Score: 8.8 (HIGH) Use-after-free vulnerability in libxml2 through 2.9.4, as used in Google Chrome before 52.0.2743.82, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the XPointer range-to function.

Nokogiri gem contains several vulnerabilities in libxml2 and libxslt Several vulnerabilities were discovered in the libxml2 and libxslt libraries that the Nokogiri gem depends on.

CVE-2015-1819 A denial of service flaw was found in the way libxml2 parsed XML documents. This flaw could cause an application that uses libxml2 to use an excessive amount of memory.

CVE-2015-7941 libxml2 does not properly stop parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and libxml2 crash) via crafted specially XML data.

CVE-2015-7942 The xmlParseConditionalSections function in parser.c in libxml2 does not properly skip intermediary entities when it stops parsing invalid input, which allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted XML data.

Revert libxml2 behavior in Nokogiri gem that could cause XSS [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:

GNOME/libxml2@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:

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.
