{"schemaVersion":3,"id":"SUSE-SU-2025:02749-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for iperf\n\nThis update for iperf fixes the following issues:\n\n- update to 3.19.1:\n  * CVE-2025-54351: Fixed buffer overflow in net.c (bsc#1247522)\n  * CVE-2025-54350: Fixed Base64Decode assertion failure and application\n    exit upon a malformed authentication attempt (bsc#1247520)\n  * CVE-2025-54349: Fixed off-by-one error and resultant heap-based\n    buffer overflow (bsc#1247519)\n\n- update to 3.19:\n  * iperf3 now supports the use of Multi-Path TCP (MPTCPv1) on Linux\n    with the use of the `-m` or `--mptcp` flag. (PR #1661)\n  * iperf3 now supports a `--cntl-ka` option to enable TCP keepalives\n    on the control connection. (#812, #835, PR #1423)\n  * iperf3 now supports the `MSG_TRUNC` receive option, specified by\n    the `--skip-rx-copy`. This theoretically improves the rated\n    throughput of tests at high bitrates by not delivering network\n    payload data to userspace. (#1678, PR #1717)\n  * A bug that caused the bitrate setting to be ignored when bursts\n    are set, has been fixed. (#1773, #1820, PR #1821, PR #1848)\n  * The congestion control protocol setting, if used, is now\n    properly reset between tests. (PR #1812)\n  * iperf3 now exits with a non-error 0 exit code if exiting via a\n    `SIGTERM`, `SIGHUP`, or `SIGINT`. (#1009, PR# 1829)\n  * The current behavior of iperf3 with respect to the `-n` and `-k`\n    options is now documented as correct.
