Vulnerabilidad de formato de cadena en stream.c en la extensión phar en PHP v5.3.x hasta v5.3.3 permite a atacantes dependientes del contexto obtener información sensible (contenidos de memoria) y probablemente ejecutar código de su elección a través de URI phar:// manipuladas que no manejan adecuadamente por la función har_stream_flush, dando lugar a errores en la función php_stream_wrapper_log_error. NOTA: Esta vulnerabilidad existe por una solución incompleta para CVE-2010-2094.
