    Iperf is a tool which can measure maximum TCP bandwidth and tune various parameters and UDP     characteristics. Iperf reports bandwidth, delay jitter, and data-gram loss.

    Security Fix(es):

    * iperf3: possible denial of service (CVE-2023-7250,ESNET-SECADV-2023-0002)

    * iperf3: vulnerable to marvin attack if the authentication option is used (CVE-2024-26306)

The version of iperf3 installed on the remote host is prior to 3.1.7-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2579 advisory.

    It is possible for a malicious or malfunctioning client to send lessthan the expected amount of data to     the server. If this happens, theserver will hang indefinitely waiting for the remainder (or until     theconnection gets closed). Because iperf3 is deliberately designed toservice only one client connection     at a time, this will prevent otherconnections to the iperf3 server.Avoid running iperf3 with root     privileges to minimize impact.Update iperf3 to a version containing the fix (i.e. iperf-3.15 orlater).

The version of iperf3 installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-7250 advisory.

  - A flaw was found in iperf, a utility for testing network performance using TCP, UDP, and SCTP. A malicious     or malfunctioning client can send less than the expected amount of data to the iperf server, which can     cause the server to hang indefinitely waiting for the remainder or until the connection gets closed. This     will prevent other connections to the server, leading to a denial of service. (CVE-2023-7250)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in iperf, a utility for testing network performance using TCP, UDP, and SCTP. A malicious     or malfunctioning client can send less than the expected amount of data to the iperf server, which can     cause the server to hang indefinitely waiting for the remainder or until the connection gets closed. This     will prevent other connections to the server, leading to a denial of service. (CVE-2023-7250)

Note that Nessus relies on the presence of the package as reported by the vendor.

    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
