The xsl_ext_function_php function in ext/xsl/xsltprocessor.c in PHP before
5.4.45, 5.5.x before 5.5.29, and 5.6.x before 5.6.13, when libxml2 before
2.9.2 is used, does not consider the possibility of a NULL valuePop return
value before proceeding with a free operation after the principal argument
loop, which allows remote attackers to cause a denial of service (NULL
pointer dereference and application crash) via a crafted XML document, a
different vulnerability than CVE-2015-6837.
