漏洞描述
中文描述:

Microsoft DNS Server是美国微软(Microsoft)公司的一个服务。 Microsoft DNS Server存在安全漏洞。以下产品和版本受到影响:Windows Server 2019,Windows Server 2019 (Server Core installation),Windows Server 2022,Windows Server 2022 (Server Core installation),Windows Server 2022, 23H2 Edition (Server Core installation),Windows Server 2016,Windows Server 2016 (Server Core installation),Windows Server 2008 R2 for x64-based Systems Service Pack 1,Windows Server 2008 R2 for x64-based Systems Service Pack 1 (Server Core installation),Windows Server 2012,Windows Server 2012 (Server Core installation),Windows Server 2012 R2,Windows Server 2012 R2 (Server Core installation)。

英文描述:

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 records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records.
