    Package        : iperf3
    Version        : 3.9-1+deb11u2
    CVE ID         : CVE-2023-7250 CVE-2024-26306 CVE-2024-53580
    Debian Bug     : 1071751 1090931

    Several security vulnerabilities have been discovered in iperf3, an internet
    protocol bandwidth measuring tool, which may lead to a denial-of-service. When
    iperf3 was used as a server with RSA authentication CVE-2024-26306 allowed a
    timing side channel attack in RSA decryption operations sufficient for an
    attacker to recover credential plaintext.

    For Debian 11 bullseye, these problems have been fixed in version
    3.9-1+deb11u2.

    We recommend that you upgrade your iperf3 packages.

    For the detailed security status of iperf3 please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/iperf3
