Changes with nginx 1.4.7 18 Mar 2014 *) Security: a heap memory buffer overflow might occur in a worker process while handling a specially crafted request by ngx_http_spdy_module, potentially resulting in arbitrary code execution (CVE-2014-0133). Thanks to Lucas Molas, researcher at Programa STIC, Fundación Dr. Manuel Sadosky, Buenos Aires, Argentina. *) Bugfix: in the "fastcgi_next_upstream" directive. Thanks to Lucas Molas. Changes with nginx 1.4.6 04 Mar 2014 *) Bugfix: the "client_max_body_size" directive might not work when reading a request body using chunked transfer encoding; the bug had appeared in 1.3.9. Thanks to Lucas Molas. *) Bugfix: a segmentation fault might occur in a worker process when proxying WebSocket connections.相比Nginx1.4.6提高了安全性,修正了fastcgi_next_upstream指令。 下面就给Nginx1.4.6做个平滑升级,将其升级至Nginx1.4.7版本,如图:
