🚨 Your current dependencies have known security vulnerabilities 🚨
This dependency update fixes known security vulnerabilities. Please see the details below and assess their impact carefully. We recommend to merge and deploy this as soon as possible!
Here is everything you need to know about this update. Please take a good look at what changed and the test results before merging this pull request.
Please note that this advisory only applies to the CRuby implementation
of Nokogiri, and only if the packaged libraries are 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.
JRuby users are not affected.
Severity
The Nokogiri maintainers have evaluated this as Moderate.
Impact
From the CVE description, this issue applies to the xmlTextReader
module (which underlies Nokogiri::XML::Reader):
When using the XML Reader interface with DTD validation and
XInclude expansion enabled, processing crafted XML documents
can lead to an xmlValidatePopElement use-after-free.
Mitigation
Upgrade to Nokogiri ~> 1.15.6 or >= 1.16.2.
Users who are unable to upgrade Nokogiri may also choose a more
complicated mitigation: compile and link Nokogiri against patched
external libxml2 libraries which will also address these same issues.
Please note that this advisory only applies to the CRuby implementation of
Nokogiri < 1.16.2, and only if the packaged libraries are 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.
Severity
The Nokogiri maintainers have evaluated this as Moderate.
Mitigation
Upgrade to Nokogiri >= 1.16.2.
Users who are unable to upgrade Nokogiri may also choose a more complicated
mitigation: compile and link Nokogiri against external libraries libxml2 >=
2.12.5 which will also address these same issues.
[CRuby] XML::Reader sets the @encoding instance variable during reading if it is not passed into the initializer. Previously, it would remain nil. The behavior of Reader#encoding has not changed. This works around changes to how libxml2 reports the encoding used in v2.12.6.
[CRuby] XML::Reader defaults the encoding to UTF-8 if it's not specified in either the document or as a method parameter. Previously non-ASCII characters were serialized as NCRs in this case. [#2891] (@flavorjones)
[CRuby] Restored support for compilation by GCC versions earlier than 4.6, which was broken in v1.15.0 (540e9ae). [#3090] (@adfoster-r7)
[CRuby] Patched upstream libxml2 to allow parsing HTML5 in the context of a namespaced node (e.g., foreign content like MathML). [#3112, #3116] (@flavorjones)
[CRuby] Fixed a small memory leak in libgumbo (HTML5 parser) when the maximum tree depth limit is hit. [#3098, #3100] (@stevecheckoway)
This version marks official support for the pattern matching API in XML::Attr, XML::Document, XML::DocumentFragment, XML::Namespace, XML::Node, and XML::NodeSet (and their subclasses), originally introduced as an experimental feature in v1.14.0. (@flavorjones)
CSS nth pseudo-classes now handle spaces, e.g. "2n + 1". [#3018] (@fusion2004)
[CRuby] libgumbo no longer leaks memory when an incomplete tag is abandoned by the HTML5 parser. [#3036] (@flavorjones)
Removed
Removed Nokogiri::HTML5.get which was deprecated in v1.12.0. [#2278] (@flavorjones)
Removed the CSS-to-XPath utility modules XPathVisitorAlwaysUseBuiltins and XPathVisitorOptimallyUseBuiltins, which were deprecated in v1.13.0 in favor of XPathVisitor constructor args. [#2403] (@flavorjones)
Removed XML::Reader#attribute_nodes which was deprecated in v1.13.8 in favor of #attribute_hash. [#2598, #2599] (@flavorjones)
[CRuby] Removed the libxml/libxml2_path key from VersionInfo, used in the past for third-party library integration, in favor of the nokogiri/cppflags and nokogiri/ldflags keys. Please note that third-party library integration is not fully supported and may be deprecated soon, see #2746 for more context. [#2143] (@flavorjones)
