Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1197 advisory.

In iperf before 3.19.1, iperf_auth.c has an off-by-one error and resultant heap-based buffer overflow.
(CVE-2025-54349)

In iperf before 3.19.1, iperf_auth.c has a Base64Decode assertion failure and application exit upon a malformed authentication attempt. (CVE-2025-54350)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'dnf update iperf3 --releasever 2023.9.20250929' or or 'dnf update --advisory ALAS2023-2025-1197 --releasever 2023.9.20250929' to update your system.
