Summary
iperf3 vulnerabilities
Details

Jorge Sancho Larraz discovered that iperf3 did not properly manage certain inputs, which could cause the server process to stop responding, waiting for input on the control connection. A remote attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 22.04 LTS. (CVE-2023-7250)

It was discovered that iperf3 had a timing side-channel when performing RSA decryption. An attacker could possibly use this issue to recover sensitive information. This issue was only addressed in Ubuntu 20.04 LTS and Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-26306)

It was discovered that iperf3 incorrectly handled certain inputs. An attacker could possibly use this issue to cause a denial of service. This issue was only addressed in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. (CVE-2024-53580)

Han Lee discovered that iperf3 had an off-by-one heap overflow. An attacker could possibly use this issue to crash the program or execute arbitrary code. This issue was only addressed in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 24.04 LTS and Ubuntu 25.10. (CVE-2025-54349)

Han Lee discovered that iperf3 did not properly manage certain inputs. An attacker could possibly use this issue to cause a denial of service. (CVE-2025-54350)
