Debian DLA-229-1 : libnokogiri-ruby security update

high Nessus Plugin ID 83864


The remote Debian host is missing a security update.


An XML eXternal Entity (XXE) flaw was found in Nokogiri, a Ruby gem for parsing HTML, XML, and SAX. Using external XML entities, a remote attacker could specify a URL in a specially crafted XML that, when parsed, would cause a connection to that URL to be opened.

This update enables the 'nonet' option by default (and provides new methods to disable default options if needed).

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected packages.
