リリースノート
Security notes
- Thanks to Claude and Ada Logics for finding and reporting two potential security vulnerabilities. One is a remote use-after-free in iperf_server_api.c (ANT-2026-E5BA80X9 / CVE-2026-101283) and the other is a heap buffer overflow in iperf_auth.c (ANT-2026-FXH14FHV / CVE-2026-101276).
- Thanks to Justin Stitt for reporting and fixing a heap-buffer overflow was fixed in iperf_auth.c (PR #2027).
- Thanks to Ravindu Lakmina Munaweera (Github: @Ravi-lk) for reporting and fixing a DOS infinite-loop (CVE-2026-102253).
- Thanks to Dirk Müller for finding and reporting an issue with test parameters (PR #2039, CVE-2026-71217).
- The iperf-3.18 release notes were updated to reflect that a code change in that version addresses CVE-2026-71218.
Notable user-visible changes
- Attempting to set zero parallel streams is no longer allowed (PR #2048).
- Zerocopy and rx-copy are now allowed in the case of reverse direction tests and the server (sending side) supports these features but the client (receiving side) does not (#2045, PR #2044).
- The limit on GSO_MAX_DG_IN_BF was fixed to limit the number of segments to the maximum allowed (#2032 / PR #2033). This change unbreaks GSO for small message sizes.
Notable developer-visible changes
- In iperf_auth.c, in addition to fixing the heap buffer overflow, the return value of several functions is checked (PR #2046, PR #2040).
- Several file descriptor leaks have been fixed (PR #2034).
- In iperf_tcp, connections now timeout to prevent a race condition in accepting new connections to avoid a deadlock (#2029, PR #2030).
- Periodic timers are now cancelled at the end of a test (#2018, PR #2021).
- DSCP/TOS is now correctly set in the first UDP/TCP stream packet (#510, #830, PR #2047).
