Ubuntu 16.04 LTS / 18.04 LTS / 19.04 : nginx vulnerabilities (USN-4099-1) (0-Length Headers Leak) (Data Dribble) (Resource Loop)

High Nessus Plugin ID 128024

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected packages.
