The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by a vulnerability as referenced in the USN-6431-1 advisory.

  • iperf3 before 3.14 allows peers to cause an integer overflow and heap corruption via a crafted length field. (CVE-2023-38403)

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