<p>An update that solves three vulnerabilities can now be installed.</p>
<h2>Description:</h2>
<p>This update for iperf fixes the following issues:</p>
<ul>
<li>update to 3.19.1:</li>
<li>CVE-2025-54351: Fixed buffer overflow in net.c (bsc#1247522)</li>
<li>CVE-2025-54350: Fixed Base64Decode assertion failure and application
exit upon a malformed authentication attempt (bsc#1247520)</li>
<li>
<p>CVE-2025-54349: Fixed off-by-one error and resultant heap-based
buffer overflow (bsc#1247519)</p>
</li>
<li>
<p>update to 3.19:</p>
</li>
<li>iperf3 now supports the use of Multi-Path TCP (MPTCPv1) on Linux
with the use of the <code>-m</code> or <code>--mptcp</code> flag. (PR #1661)</li>
<li>iperf3 now supports a <code>--cntl-ka</code> option to enable TCP keepalives
on the control connection. (#812, #835, PR #1423)</li>
<li>iperf3 now supports the <code>MSG_TRUNC</code> receive option, specified by
the <code>--skip-rx-copy</code>. This theoretically improves the rated
throughput of tests at high bitrates by not delivering network
payload data to userspace. (#1678, PR #1717)</li>
<li>A bug that caused the bitrate setting to be ignored when bursts
are set, has been fixed. (#1773, #1820, PR #1821, PR #1848)</li>
<li>The congestion control protocol setting, if used, is now
properly reset between tests. (PR #1812)</li>
<li>iperf3 now exits with a non-error 0 exit code if exiting via a
<code>SIGTERM</code>, <code>SIGHUP</code>, or <code>SIGINT</code>. (#1009, PR# 1829)</li>
<li>The current behavior of iperf3 with respect to the <code>-n</code> and <code>-k</code>
options is now documented as correct. (#1768, #1775, #596, PR #1800)</li>
</ul>
