USN-3114-2: nginx regression

27 October 2016

nginx regression

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 16.10
  • Ubuntu 16.04 LTS
  • Ubuntu 14.04 LTS


USN-3114-1 introduced a regression in nginx packaging.

Software Description

  • nginx - small, powerful, scalable web/proxy server


USN-3114-1 fixed a vulnerability in nginx. A packaging issue prevented nginx from being reinstalled or upgraded to a subsequent release. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

Dawid Golunski discovered that the nginx package incorrectly handled log file permissions. A remote attacker could possibly use this issue to obtain root privileges.
