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 libxmldisableentityloader 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.
crypto/x509/x509vfy.c in OpenSSL 1.0.2i allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) by triggering a CRL operation.
/ext/phar/pharobject.c in PHP 7.0.7 and 5.6.x allows remote attackers to execute arbitrary code. NOTE: Introduced as part of an incomplete fix to CVE-2015-6833.
