Descriptions

In PHP before 5.6.31, 7.x before 7.0.21, and 7.1.x before 7.1.7, a stack-based buffer overflow in the zend_ini_do_op() function in Zend/zend_ini_parser.c could cause a denial of service or potentially allow executing code. NOTE: this is only relevant for PHP applications that accept untrusted input (instead of the system's php.ini file) for the parse_ini_string or parse_ini_file function, e.g., a web application for syntax validation of php.ini directives.

En PHP, en versiones anteriores a la 5.6.31, versiones 7.x anteriores a la 7.0.21 y versiones 7.1.x anteriores a la 7.1.7, un desbordamiento de búfer basado en pila en la función zend_ini_do_op() en Zend/zend_ini_parser.c podría provocar una denegación de servicio (DoS) o, posiblemente, permitir la ejecución de código. NOTA: esto solo es relevante en aplicaciones PHP que aceptan entradas no fiables (en lugar del archivo php.ini del sistema) para las funciones parse_ini_string o parse_ini_file. Por ejemplo, una aplicación web para la validación sintáctica de directivas php.ini.
