Descriptions
PHP 5.3.8 does not always check the return value of the zend_strndup function, which might allow remote attackers to cause a denial of service (NULL pointer dereference and application crash) via crafted input to an application that performs strndup operations on untrusted string data, as demonstrated by the define function in zend_builtin_functions.c, and unspecified functions in ext/soap/php_sdl.c, ext/standard/syslog.c, ext/standard/browscap.c, ext/oci8/oci8.c, ext/com_dotnet/com_typeinfo.c, and main/php_open_temporary_file.c.
PHP v5.3.8 no siempre comprueba el valor devuelto de la función zend_strndup, lo que podría permitir a atacantes remotos provocar una denegación de servicio (borrado de referencia a puntero nulo y caída de la aplicación) a través de una entrada especificamente diseñada para este fin a una aplicación que realiza operaciones de 'strndup' (duplicación) de cadenas de datos no confiables. Esto se puede demostrar con la función 'define' en zend_builtin_functions.c, y funciones no especificadas en ext/soap/php_sdl.c, ext/standard/syslog.c, ext/standard/browscap.c, ext/oci8/oci8.c, ext/com_dotnet/com_typeinfo.c y main/php_open_temporary_file.c.
PHP version 5.3.8 suffers from multiple NULL pointer dereference vulnerabilities.
