nginx regression
===========================================================================

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

- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

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

Software Description:
- nginx: small, powerful, scalable web/proxy server

Details:

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.
