"The remote Ubuntu 22.04 LTS / 23.04 host has packages installed that are affected by a vulnerability as referenced in

    USN-6431-1 fixed a vulnerability in iperf3. This update provides the corresponding update for Ubuntu 22.04
    LTS and Ubuntu 23.04.

    Original advisory details:

    It was discovered that iperf3 did not properly manage certain inputs,

    which could lead to a crash. A remote attacker could possibly use this

    issue to cause a denial of service. (CVE-2023-38403)

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

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
