## Description

The SOAP parser in PHP before 5.3.23 and 5.4.x before 5.4.13 allows remote
attackers to read arbitrary files via a SOAP WSDL file containing an XML
external entity declaration in conjunction with an entity reference,
related to an XML External Entity (XXE) issue in the soap\_xmlParseFile and
soap\_xmlParseMemory functions. NOTE: this vulnerability exists because of
an incorrect fix for CVE-2013-1824.
