USN-3114-2: nginx regression

Releases

• Ubuntu 16.10
• Ubuntu 16.04 ESM
• Ubuntu 14.04 ESM

Packages

• 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.
