Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2991-1 advisory.

 It was discovered that nginx incorrectly handled saving client request bodies to temporary files. A remote attacker could possibly use this issue to cause nginx to crash, resulting in a denial of service.
