Ubuntu Security Notice USN-4099-1
August 15, 2019

nginx vulnerabilities
==========================================================================

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

– Ubuntu 19.04
– Ubuntu 18.04 LTS
– Ubuntu 16.04 LTS

Summary:

nginx could be made to crash if it received specially crafted network
traffic.

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

Details:

Jonathan Looney discovered that nginx incorrectly handled the HTTP/2
implementation. A remote attacker could possibly use this issue to consume
resources, leading to a denial of service.

Update instructions:

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

Ubuntu 19.04:
nginx-common 1.15.9-0ubuntu1.1
nginx-core 1.15.9-0ubuntu1.1
nginx-extras 1.15.9-0ubuntu1.1
nginx-full 1.15.9-0ubuntu1.1
nginx-light 1.15.9-0ubuntu1.1

Ubuntu 18.04 LTS:
nginx-common 1.14.0-0ubuntu1.4
nginx-core 1.14.0-0ubuntu1.4
nginx-extras 1.14.0-0ubuntu1.4
nginx-full 1.14.0-0ubuntu1.4
nginx-light 1.14.0-0ubuntu1.4

Ubuntu 16.04 LTS:
nginx-common 1.10.3-0ubuntu0.16.04.4
nginx-core 1.10.3-0ubuntu0.16.04.4
nginx-extras 1.10.3-0ubuntu0.16.04.4
nginx-full 1.10.3-0ubuntu0.16.04.4
nginx-light 1.10.3-0ubuntu0.16.04.4

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