Debian DLA-2680-1 : nginx security update

critical Nessus Plugin ID 150336


New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security update.


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.

For the detailed security status of nginx please refer to its security tracker page at:

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Upgrade the affected packages.
