HCE3-SA-2025-0063 Critical HCE 3.0 Security Fix(es): In iperf before 3.19.1, iperf_auth.c has an off-by-one error and resultant heap-based buffer overflow. (CVE-2025-54349) iperf v3.17.1 was discovered to contain a segmentation violation via the iperf_exchange_parameters() function. (CVE-2024-53580) 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. (CVE-2024-26306) In iperf before 3.19.1, iperf_auth.c has a Base64Decode assertion failure and application exit upon a malformed authentication attempt.
