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

Ubuntu 19.04

Summary

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

Software Description

implementation. A remote attacker could possibly use this issue to consume
resources, leading to a denial of service.
