The remote Redhat Enterprise Linux 6 / 7 / 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:5982 advisory.
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)
* openssl: c_rehash script allows command injection (CVE-2022-1292)
* openssl: the c_rehash script allows command injection (CVE-2022-2068)
* golang: net/http: excessive memory growth in a Go server accepting HTTP/2 requests (CVE-2022-41717)
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.
Bug Fix(es):
* Katello Agent / Goferd Service CLOSE_WAIT Connections on RHEL8 Clients (BZ#2184996)
* Not possible to configure the temporary directory to be used on clients by remote execution in pull mode (BZ#2217079)
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.
