The Ubuntu security team deemed this advisory irrelevant for Ubuntu:15.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream php5 package and not the php5 package as distributed by Ubuntu.
ext/libxml/libxml.c in PHP before 5.5.22 and 5.6.x before 5.6.6, when PHP-FPM is used, does not isolate each thread from libxml_disable_entity_loader changes in other threads, which allows remote attackers to conduct XML External Entity (XXE) and XML Entity Expansion (XEE) attacks via a crafted XML document, a related issue to CVE-2015-5161.
