The remote Redhat Enterprise Linux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2024:2729 advisory.

A highly-available key value store for shared configuration

Security Fix(es):

* golang-fips/openssl: Memory leaks in code encrypting and decrypting RSA payloads (CVE-2024-1394)

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

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

* net/http, x/net/http2: unlimited number of CONTINUATION frames causes DoS (CVE-2023-45288)

* etcd: Incomplete fix for CVE-2023-39325/CVE-2023-44487 in OpenStack Platform  (CVE-2024-4438)

For more details about the security issue(s), including the impact, a CVSS     score, acknowledgments, and other related information, refer to the CVE     page listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.
