Due to unrestricted entity expansion, when reading text nodes from an XML

large string objects which can consume all of the memory on a machine,
causing a denial of service (CVE-2014-8080).

The Mageia 3 ruby package has been updated to 1.9.3-p550 and the Mageia 4
ruby package has been updated to 2.0.0-p594 to fix this issue and several
other bugs.");
