spl_array.c in the SPL extension in PHP before 5.5.37 and 5.6.x before
5.6.23 improperly interacts with the unserialize implementation and garbage
collection, which allows remote attackers to execute arbitrary code or
cause a denial of service (use-after-free and application crash) via
crafted serialized data.
