		<Note Title="Synopsis" Type="General" Ordinal="1" xml:lang="en">rubygem-nokogiri security update</Note>
		<Note Title="Summary" Type="General" Ordinal="2" xml:lang="en">An update for rubygem-nokogiri is now available for openEuler-20.03-LTS-SP1.</Note>
		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">Nokogiri parses and searches XML/HTML very quickly, and also has correctly implemented CSS3 selector support as well as XPath support. Nokogiri also features an Hpricot compatibility layer to help ease the change to using correct CSS and XPath.

Security Fix(es):

Nokogiri is a Rubygem providing HTML, XML, SAX, and Reader parsers with XPath and CSS selector support. In Nokogiri before version 1.11.0.rc4 there is an XXE vulnerability. 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. This is fixed in Nokogiri version 1.11.0.rc4.(CVE-2020-26247)</Note>
