support to read, modify and write XML and HTML files. A remote
attacker could provide a specially crafted XML file that, when
processed by an application using libxml2, would lead to excessive CPU
consumption (denial of service) based on excessive entity
substitutions, even if entity substitution was disabled, which is the
parser default behavior. (CVE-2014-3660)
