Original Advisory:

Comment 1 Ratul Gupta 2013-12-26 13:18:48 UTC
Created rubygem-nokogiri tracking bugs for this issue:

Affects: fedora-all [bug 1046665]

Comment 2 Mamoru TASAKA 2013-12-26 14:43:03 UTC
Would you confirm if this really affects fedora? Upstream info says JRuby extension is affected, patches are for .java files, however fedora (at least fedora's rubygem-nokogiri srpm) does not ship nokogiri JRuby extension.
Java files are included in http://rubygems.org/downloads/nokogiri-1.5.11-java.gem or so, however fedora srpm does not use this, and uses http://rubygems.org/downloads/nokogiri-1.5.9.gem or so.

Again setting needinfo.

Comment 6 Vincent Danen 2014-01-23 19:22:11 UTC
This issue does not affect anything we ship.  While the nokogiri rubygem is included in Fedora and EPEL, there is no JRuby implementation provided on either platform.
