{"id":"UBUNTU-CVE-2024-26306","details":"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.","modified":"2026-04-22T17:39:03.004007Z","published":"2024-05-14T15:08:00Z","related":["USN-7970-1"],"upstream":["CVE-2024-26306"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-26306"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-26306"},{"type":"REPORT","url":"https://downloads.es.net/pub/iperf/esnet-secadv-2024-0001.txt.asc"},{"type":"REPORT","url":"https://github.com/esnet/iperf/releases/tag/3.17"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7970-1"}],"affected":[{"package":{"name":"iperf3","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/iperf3@3.0.11-1ubuntu0.1~esm2?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.0.11-1","3.0.11-1ubuntu0.1~esm1","3.0.11-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"iperf3","binary_version":"3.0.11-1ubuntu0.1~esm2"},{"binary_name":"libiperf0","binary_version":"3.0.11-1ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-26306.json"}},{"package":{"name":"iperf3","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/iperf3@3.1.3-1ubuntu0.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.3-1","3.1.3-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"iperf3","binary_version":"3.1.3-1ubuntu0.1~esm1"},{"binary_name":"libiperf0","binary_version":"3.1.3-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-26306.json"}},{"package":{"name":"iperf3","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/iperf3@3.7-3ubuntu0.1~esm2?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7-3ubuntu0.1~esm2"}]}],"versions":["3.6-2","3.7-1","3.7-2","3.7-3","3.7-3ubuntu0.1~esm1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"iperf3","binary_version":"3.7-3ubuntu0.1~esm2"},{"binary_name":"libiperf0","binary_version":"3.7-3ubuntu0.1~esm2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-26306.json"}},{"package":{"name":"iperf3","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/iperf3@3.9-1+deb11u1ubuntu0.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9-1+deb11u1ubuntu0.1"}]}],"versions":["3.9-1","3.9-1build1","3.9-1+deb11u1build0.22.04.1"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"iperf3","binary_version":"3.9-1+deb11u1ubuntu0.1"},{"binary_name":"libiperf0","binary_version":"3.9-1+deb11u1ubuntu0.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-26306.json"}},{"package":{"name":"iperf3","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/iperf3@3.16-1ubuntu0.1~esm1?arch=source&distro=esm-apps/noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.16-1ubuntu0.1~esm1"}]}],"versions":["3.14-1","3.15-1","3.16-1","3.16-1build1","3.16-1build2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"iperf3","binary_version":"3.16-1ubuntu0.1~esm1"},{"binary_name":"libiperf0","binary_version":"3.16-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-26306.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
