"The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2023:7513 advisory.

  - A side channel vulnerability on some of the AMD CPUs may allow an attacker to influence the return address
    prediction. This may result in speculative execution at an attacker-controlled?address, potentially
    leading to information disclosure. (CVE-2023-20569)

  - An issue in Zen 2 CPUs, under specific microarchitectural circumstances, may allow an attacker to
    potentially access sensitive information. (CVE-2023-20593)

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