A memory corruption vulnerability exists in PHP. The vulnerability is due to type confusion in the unserialize() function. A successful attack can allow arbitrary code execution in the context of the PHP application.
The SPL component in PHP before 5.4.30 and 5.5.x before 5.5.14 incorrectly anticipates that certain data structures will have the array data type after unserialization, which allows remote attackers to execute arbitrary code via a crafted string that triggers use of a Hashtable destructor, related to "type confusion" issues in (1) ArrayObject and (2) SPLObjectStorage.
