The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:7200 advisory.

  • golang: net/http, x/net/http2: rapid stream resets can cause excessive work (CVE-2023-44487) (CVE-2023-39325)

  • golang: net/http/internal: Denial of Service (DoS) via Resource Consumption via HTTP requests (CVE-2023-39326)

  • golang: crypto/tls: Timing Side Channel attack in RSA based TLS key exchanges. (CVE-2023-45287)

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