The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:5969 advisory.

The etcd packages provide a highly available key-value store for shared configuration.

Security Fix(es):

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

* HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)     (CVE-2023-44487)

* golang: crypto/tls: slow verification of certificate chains containing large RSA keys (CVE-2023-29409)

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