CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-2906 – Memory leaks in code handling Diffie-Hellman key exchange via TKEY RRs (OpenSSL 3.0.0+ only)
https://notcve.org/view.php?id=CVE-2022-2906
An attacker can leverage this flaw to gradually erode available memory to the point where named crashes for lack of resources. Upon restart the attacker would have to begin again, but nevertheless there is the potential to deny service. Un atacante puede aprovechar este fallo para erosionar gradualmente la memoria disponible hasta el punto de que named sea bloqueado por falta de recursos. Al reiniciar, el atacante tendría que empezar de nuevo, pero sin embargo se presenta la posibilidad de denegar el servicio • http://www.openwall.com/lists/oss-security/2022/09/21/3 https://kb.isc.org/docs/cve-2022-2906 https://security.gentoo.org/glsa/202210-25 • CWE-401: Missing Release of Memory after Effective Lifetime •

CVSS: 7.5EPSS: 0%CPEs: 12EXPL: 0CVE-2022-1183 – Destroying a TLS session early causes assertion failure
https://notcve.org/view.php?id=CVE-2022-1183
On vulnerable configurations, the named daemon may, in some circumstances, terminate with an assertion failure. Vulnerable configurations are those that include a reference to http within the listen-on statements in their named.conf. TLS is used by both DNS over TLS (DoT) and DNS over HTTPS (DoH), but configurations using DoT alone are unaffected. Affects BIND 9.18.0 -> 9.18.2 and version 9.19.0 of the BIND 9.19 development branch. En configuraciones vulnerables, el demonio nombrado puede, en algunas circunstancias, terminar con un fallo de aserción. • https://kb.isc.org/docs/cve-2022-1183 https://security.netapp.com/advisory/ntap-20220707-0002 • CWE-617: Reachable Assertion •
