Zend/zend_hash.c in PHP before 7.0.15 and 7.1.x before 7.1.1 mishandles
certain cases that require large array allocations, which allows remote
attackers to execute arbitrary code or cause a denial of service (integer
overflow, uninitialized memory access, and use of arbitrary destructor
function pointers) via crafted serialized data.
