Ubuntu 16.04 LTS / 18.04 LTS : nginx vulnerabilities (USN-4099-1)

high Nessus Plugin ID 128024

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4099-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
