{"id":"SUSE-SU-2025:02749-1","summary":"Security update for iperf","details":"This 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. (#1768, #1775, #596, PR #1800)\n","modified":"2026-02-04T02:47:13.430435Z","published":"2025-08-11T07:06:39Z","related":["CVE-2025-54349","CVE-2025-54350","CVE-2025-54351"],"upstream":["CVE-2025-54349","CVE-2025-54350","CVE-2025-54351"],"references":[{"type":"ADVISORY","url":"https://www.suse.com/support/update/announcement/2025/suse-su-202502749-1/"},{"type":"REPORT","url":"https://bugzilla.suse.com/1247519"},{"type":"REPORT","url":"https://bugzilla.suse.com/1247520"},{"type":"REPORT","url":"https://bugzilla.suse.com/1247522"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2025-54349"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2025-54350"},{"type":"WEB","url":"https://www.suse.com/security/cve/CVE-2025-54351"}],"affected":[{"package":{"name":"iperf","ecosystem":"SUSE:Linux Enterprise Module for Package Hub 15 SP6","purl":"pkg:rpm/suse/iperf&distro=SUSE%20Linux%20Enterprise%20Module%20for%20Package%20Hub%2015%20SP6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.19.1-150000.3.15.1"}]}],"ecosystem_specific":{"binaries":[{"libiperf0":"3.19.1-150000.3.15.1","iperf":"3.19.1-150000.3.15.1","iperf-devel":"3.19.1-150000.3.15.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2025:02749-1.json"}},{"package":{"name":"iperf","ecosystem":"SUSE:Linux Enterprise Module for Package Hub 15 SP7","purl":"pkg:rpm/suse/iperf&distro=SUSE%20Linux%20Enterprise%20Module%20for%20Package%20Hub%2015%20SP7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.19.1-150000.3.15.1"}]}],"ecosystem_specific":{"binaries":[{"libiperf0":"3.19.1-150000.3.15.1","iperf":"3.19.1-150000.3.15.1","iperf-devel":"3.19.1-150000.3.15.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2025:02749-1.json"}},{"package":{"name":"iperf","ecosystem":"SUSE:Enterprise Storage 7.1","purl":"pkg:rpm/suse/iperf&distro=SUSE%20Enterprise%20Storage%207.1"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.19.1-150000.3.15.1"}]}],"ecosystem_specific":{"binaries":[{"libiperf0":"3.19.1-150000.3.15.1","iperf":"3.19.1-150000.3.15.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2025:02749-1.json"}},{"package":{"name":"iperf","ecosystem":"openSUSE:Leap 15.6","purl":"pkg:rpm/opensuse/iperf&distro=openSUSE%20Leap%2015.6"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.19.1-150000.3.15.1"}]}],"ecosystem_specific":{"binaries":[{"libiperf0":"3.19.1-150000.3.15.1","iperf":"3.19.1-150000.3.15.1","iperf-devel":"3.19.1-150000.3.15.1"}]},"database_specific":{"source":"https://ftp.suse.com/pub/projects/security/osv/SUSE-SU-2025:02749-1.json"}}],"schema_version":"1.7.3"}
