Description

Security update for iperf This update for iperf fixes the following issues: - 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)
