CBL Mariner 2.0 Security Update: iperf3 (CVE-2023-7250)

medium Nessus Plugin ID 201271

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of iperf3 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-7250 advisory.

 - A flaw was found in iperf, a utility for testing network performance using TCP, UDP, and SCTP. A malicious or malfunctioning client can send less than the expected amount of data to the iperf server, which can cause the server to hang indefinitely waiting for the remainder or until the connection gets closed. This will prevent other connections to the server, leading to a denial of service. (CVE-2023-7250)

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

Solution

Update the affected packages.
