Descriptions

The scan function in ext/date/lib/parse_iso_intervals.c in PHP through 5.5.6 does not properly restrict creation of DateInterval objects, which might allow remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted interval specification.

La función de análisis en ext/date/lib/parse_iso_intervals.c de PHP hasta la versión 5.5.6 no restringe adecuadamente la creación de objetos DateInterval, lo que podría permitir a atacantes remotos provocar una denegación de servicio (desbordamiento de búfer basado en memoria dinámica) a través de una especificación de intervalo manipulada.

A buffer over-read flaw was found in the way the DateInterval class parsed interval specifications. An attacker able to make a PHP application parse a specially crafted specification using DateInterval could possibly cause the PHP interpreter to crash.
