The zend_string_extend function in Zend/zend_string.h in PHP through 7.1.5 does not prevent changes to string objects that result in a negative length, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact by leveraging a script's use of .= with a long string. La función zend_string_extend en el archivo Zend/zend_string.h en PHP hasta de la versión 7.1.5 no impide cambios en los objetos de cadena que resultan en una longitud negativa, lo que permite a los atacantes remotos causar una denegación de servicio (bloqueo de aplicación) o posiblemente tener otro impacto no especificado explotando el uso de scripts .= con una cadena larga. • http://www.securityfocus.com/bid/98518 https://bugs.php.net/bug.php?id=74577 • CWE-787: Out-of-bounds Write •
