Package : ruby-nokogiri
Version : 1.6.8.1-1+deb9u1
CVE ID : CVE-2020-26247
Debian Bug : 978967
An XXE vulnerability was found in Nokogiri, a Rubygem providing HTML, XML, SAX,
and Reader parsers with XPath and CSS selector support.
XML Schemas parsed by Nokogiri::XML::Schema were trusted by default, allowing
external resources to be accessed over the network, potentially enabling XXE or
SSRF attacks. The new default behavior is to treat all input as untrusted.
The upstream advisory provides further information how to mitigate the problem
or restore the old behavior again.

For Debian 9 stretch, this problem has been fixed in version
