<p>An update that solves one vulnerability can now be installed.</p>
<h2>Description:</h2>
<p>This update for iperf fixes the following issues:</p>
<p>Update to 3.18 (bsc#1234705, CVE-2024-53580):</p>
<ul>
<li>SECURITY NOTE: Thanks to Leonid Krolle Bi.Zone for
discovering a JSON type security vulnerability that caused a
segmentation fault in the server. (CVE-2024-53580)
This has now been fixed. (PR#1810)</li>
<li>UDP packets per second now reports the correct number of
packets, by reporting NET_SOFTERROR if there's a EAGAIN/EINTR
errno if no data was sent (#1367/PR#1379).</li>
<li>Several segmentation faults related to threading were fixed.
One where <code>pthread_cancel</code> was called on an improperly
initialized thread (#1801), another where threads were being
recycled (#1760/PR#1761), and another where threads were
improperly handling signals (#1750/PR#1752).</li>
<li>A segmentation fault from calling <code>freeaddrinfo</code> with <code>NULL</code>
was fixed (PR#1755).</li>
<li>Some JSON options were fixed, including checking the size for
<code>json_read</code> (PR#1709), but the size limit was removed for
received server output (PR#1779).</li>
<li>A rcv-timeout error has been fixed. The Nread timeout was
hardcoded and timed out before the <code>--rcv-timeout</code> option</li>
<li>There is no longer a limit on the omit time period</li>
<li>Fixed an output crash under 32-bit big-endian systems</li>
<li>An issue was fixed where CPU utilization was unexpectedly
high during limited baud rate tests. The <code>--pacing-timer</code>
option was removed, but it is still available in the library</li>
<li>Add SCTP information to <code>--json</code> output and fixed compile
error when SCTP is not supported (#1731).</li>
<li>
<p><code>--fq-rate</code> was changed from a uint to a uint64 to allow
pacing above 32G. Not yet tested on big-endian systems</p>
</li>
<li>
<p>Build with OpenSSL for key based authentication support</p>
</li>
</ul>
