CVE-2023-50868
CVE-2023-50868 is a DNSSEC-related denial of service issue (NSEC3 Closest Encloser proof) that can cause CPU exhaustion. The connected documents confirm impact on DNS implementations such as Unbound and BIND/BIND9 and describe the root cause as processors performing thousands of hash iterations f...
CVE-2023-50387
Certain DNSSEC aspects of the DNS protocol in RFC 4033, 4034, 4035, 6840, and related RFCs allow remote attackers to cause a denial of service CPU consumption via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG...
