An HTTP request smuggling issue was discovered in the ngx_lua plugin for nginx, a high-performance web and reverse proxy server, as demonstrated by the ngx.location.capture API.
For Debian 9 stretch, this problem has been fixed in version 1.10.3-1+deb9u5.
We recommend that you upgrade your nginx packages.
For the detailed security status of nginx please refer to its security tracker page at: https://security-tracker.debian.org/tracker/nginx
