Comment 2 Fedora Update System 2015-05-10 23:34:10 UTC 
perl-XML-LibXML-2.0119-1.fc21 has been pushed to the Fedora 21 stable repository.  If problems still persist, please make note of it in this bug report.
Comment 3 Kurt Seifried 2015-08-07 00:01:02 UTC 
Mitigations:

This issue only affects programs using this program in forms such as:

$parser = XML::LibXML->new

or 

$XML_DOC = $parser->load_xml

if you use the form:

$XML_DOC = XML::LibXML->load_xml

this vulnerability will not be exposed.
