USN-4235-1 fixed a vulnerability in nginx. This update provides the corresponding update for Ubuntu 14.04 ESM.

Original advisory details:

Bert JW Regeer and Francisco Oca Gonzalez discovered that nginx incorrectly
handled certain error_page configurations. A remote attacker could possibly
use this issue to perform HTTP request smuggling attacks and access
resources contrary to expectations.

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 14.04 ESM:
nginx-common 1.4.6-1ubuntu3.9+esm1
nginx-core 1.4.6-1ubuntu3.9+esm1
nginx-extras 1.4.6-1ubuntu3.9+esm1
nginx-full 1.4.6-1ubuntu3.9+esm1
nginx-light 1.4.6-1ubuntu3.9+esm1

In general, a standard system update will make all the necessary changes.
