Descriptions

The zend_hash_init function in PHP 5 before 5.2.1 and PHP 4 before 4.4.5, when running on a 64-bit platform, allows context-dependent attackers to cause a denial of service (infinite loop) by unserializing certain integer expressions, which only cause 32-bit arguments to be used after the check for a negative value, as demonstrated by an "a:2147483649:{" argument.

La función zend_hash_init en PHP versión 5 anterior a 5.2.1 y PHP versión 4 anterior a 4.4.5, cuando se ejecuta en una plataforma de 64 bits, permite a los atacantes dependiendo del contexto causar una denegación de servicio (bucle infinito) al deserializar ciertas expresiones de enteros, que solo causa que argumentos de 32 bits sean usados después de la comprobación de un valor negativo, como es demostrado por un argumento "a:2147483649:{".
