   An update that fixes one vulnerability is now available.

Description:

   This update for perl-XML-Twig fixes the following issues:

   - Security fix [bsc#1008644, CVE-2016-9180]
     * Added: the no_xxe option to XML::Twig::new, which causes the parse to
       fail if external entities are used (to prevent malicious XML to access
       the filesystem).
     * Setting expand_external_ents to 0 or -1 currently doesn't work as
       expected; To completely turn off expanding external entities use
       no_xxe.
     * Update documentation for XML::Twig to mention problems with
       expand_external_ents and add information about new no_xxe argument
