Amazon Linux 2 Security Advisory: ALAS-2024-2579
Advisory Release Date: 2024-06-19 19:15 Pacific
Advisory Updated Date: 2024-06-24 16:35 Pacific
Severity: Medium

Issue Overview:

It is possible for a malicious or malfunctioning client to send less
than the expected amount of data to the server. If this happens, the
server will hang indefinitely waiting for the remainder (or until the
connection gets closed). Because iperf3 is deliberately designed to
service only one client connection at a time, this will prevent other
connections 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 or
later). (CVE-2023-7250)


Affected Packages:

iperf3


Note:

This advisory is applicable to Amazon Linux 2 (AL2) Core repository. Visit this FAQ section for the difference between AL2 Core and AL2 Extras advisories.


Issue Correction:
Run yum update iperf3 to update your system.
