"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2024:0254 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-7250:
    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-2024-26306:
    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.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
