Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES15 / openSUSE 15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2025:02749-1 advisory.

- update to 3.19.1:
* CVE-2025-54351: Fixed buffer overflow in net.c (bsc#1247522)
* CVE-2025-54350: Fixed Base64Decode assertion failure and application exit upon a malformed authentication attempt (bsc#1247520)
* CVE-2025-54349: Fixed off-by-one error and resultant heap-based buffer overflow (bsc#1247519)

- update to 3.19:
* iperf3 now supports the use of Multi-Path TCP (MPTCPv1) on Linux with the use of the `-m` or `--mptcp` flag. (PR #1661)
* iperf3 now supports a `--cntl-ka` option to enable TCP keepalives on the control connection. (#812, #835, PR #1423)
* iperf3 now supports the `MSG_TRUNC` receive option, specified by the `--skip-rx-copy`. This theoretically improves the rated throughput of tests at high bitrates by not delivering network payload data to userspace. (#1678, PR #1717)
* A bug that caused the bitrate setting to be ignored when bursts are set, has been fixed. (#1773, #1820, PR #1821, PR #1848)
* The congestion control protocol setting, if used, is now properly reset between tests. (PR #1812)
* iperf3 now exits with a non-error 0 exit code if exiting via a `SIGTERM`, `SIGHUP`, or `SIGINT`. (#1009, PR# 1829)
* The current behavior of iperf3 with respect to the `-n` and `-k` options is now documented as correct. (#1768, #1775, #596, PR #1800)

Tenable has extracted the preceding description block directly from the SUSE security advisory.

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

Solution

Update the affected iperf, iperf-devel and / or libiperf0 packages.
