iperf3 version 3.21 contains a critical remote, unauthenticated heap use-after-free vulnerability. The issue arises because the server's per-test watchdog function frees streams without properly cancelling or joining their associated worker threads, leading to a use-after-free condition when a blocked worker thread dereferences a freed iperf_stream. This vulnerability is fixed in version 3.22.

iperf v3.17.1 was discovered to contain a segmentation violation via the iperf_exchange_parameters() function.

iPerf3 before 3.17, when used with OpenSSL before 3.2.0 as a server with RSA authentication, allows a timing side channel in RSA decryption operations. This side channel could be sufficient for an attacker to recover credential plaintext. It requires the attacker to send a large number of messages for decryption, as described in "Everlasting ROBOT: the Marvin Attack" by Hubert Kario.
