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.
[MRI] Raise an exception when Nokogiri detects a specific libxml2 edge case involving blank Schema nodes wrapped by Ruby objects that would cause a segfault. Currently no fix is available upstream, so we're preventing a dangerous operation and informing users to code around it if possible. [#1985, #2001]
[JRuby] Change NodeSet#to_a to return a RubyArray instead of Object, for compilation under JRuby 9.2.9 and later. [#1968, #1969] (Thanks, @headius!)
1.10.8 / 2020-02-10

[MRI] Pulled in upstream patch from libxml that addresses CVE-2020-7595. Full details are available in #1992. Note that this patch is not yet (as of 2020-02-10) in an upstream release of libxml.
