Amazon Linux 2 : iperf3 (ALAS-2024-2579)

medium Nessus Plugin ID 200905

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of iperf3 installed on the remote host is prior to 3.1.7-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2579 advisory.

It is possible for a malicious or malfunctioning client to send lessthan the expected amount of data to the server. If this happens, theserver will hang indefinitely waiting for the remainder (or until theconnection gets closed). Because iperf3 is deliberately designed toservice only one client connection at a time, this will prevent otherconnections to the iperf3 server.Avoid running iperf3 with root privileges to minimize impact.Update iperf3 to a version containing the fix (i.e. iperf-3.15 orlater).
(CVE-2023-7250)

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

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

Solution

Run 'yum update iperf3' to update your system.
