CVE-2016-9318

Priority
Description
libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other
products, does not offer a flag directly indicating that the current
document may be read but other files may not be opened, which makes it
easier for remote attackers to conduct XML External Entity (XXE) attacks
via a crafted document.
