The deserialization code in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to cause a denial of service and execute arbitrary code via untrusted data to the unserialize function that may trigger "information disclosure, double-free and negative reference index array underflow" results.

(There is total information disclosure, resulting in all system files being revealed.)
(There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being compromised.)
(There is a total shutdown of the affected resource. The attacker can render the resource completely unavailable.)
(Specialized access conditions or extenuating circumstances do not exist. Very little knowledge or skill is required to exploit. )
(Authentication is not required to exploit the vulnerability.)
