RHSA-2023:4414: Red Hat Security Advisory: iperf3 security update

An update for iperf3 is now available for Red Hat Enterprise Linux 8.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.This content is licensed under the Creative Commons Attribution 4.0 International License (https://creativecommons.org/licenses/by/4.0/).

Related CVEs:

  • CVE-2023-38403: An integer overflow flaw was found in the way iperf3 dynamically allocates memory buffers for JSON-formatted messages. A remote attacker could send a specially crafted sequence of bytes on the iperf3 control channel with a specified JSON message length of 0xffffffff to trigger an integer overflow leading the receiving process to abort due to heap corruption. This flaw allows an attacker to use a malicious client to cause a denial of service of an iperf3 server or potentially use a malicious server to cause connecting clients to crash.
