Description
The unserialize implementation in ext/standard/var.c in PHP 7.x before 7.0.14 allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via crafted serialized data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-6834.
