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.
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.
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::XML::Schema trusts input by default, exposing risk of an XXE vulnerability
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
[CRuby] Passing non-Node objects to Document#root= now raises an ArgumentError exception. Previously this likely segfaulted. [#1900]
[JRuby] Passing non-Node objects to Document#root= now raises an ArgumentError exception. Previously this raised a TypeError exception.
[CRuby] arm64/aarch64 systems (like Apple's M1) can now compile libxml2 and libxslt from source (though we continue to strongly advise users to install the native gems for the best possible experience)
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+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:
