Package : nginx
Version : 1.10.3-1+deb9u7
CVE ID : CVE-2017-20005

Jamie Landeg-Jones and Manfred Paul discovered a buffer overflow vulnerability
in NGINX, a small, powerful, scalable web/proxy server.

NGINX has a buffer overflow for years that exceed four digits, as demonstrated
by a file with a modification date in 1969 that causes an integer overflow (or
a false modification date far in the future), when encountered by the autoindex
module.

For Debian 9 stretch, this problem has been fixed in version
1.10.3-1+deb9u7.

We recommend that you upgrade your nginx packages.
