This signature detects attempts to exploit a known vulnerability against xml_parse_into_struct() function in PHP. A successful attack can lead to arbitrary code execution.
ext/xml/xml.c in PHP before 5.3.27 does not properly consider parsing depth, which allows remote attackers to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted document that is processed by the xml_parse_into_struct function.
