CVE-2023-50868

一、漏洞信息
 漏洞编号：[CVE-2023-50868](https://nvd.nist.gov/vuln/detail/CVE-2023-50868)
 漏洞归属组件：[dhcp](https://gitee.com/src-openeuler/dhcp)
 漏洞归属的版本：4.4.2,4.4.3
 CVSS V2.0分值：
 BaseScore：0.0 Low
 Vector：CVSS：2.0/
 漏洞简述：
 The Closest Encloser Proof aspect of the DNS protocol (in RFC 5155 when RFC 9276 guidance is skipped) allows remote attackers to cause a denial of service (CPU consumption for SHA-1 computations) via DNSSEC responses in a random subdomain attack, aka the NSEC3 issue. The RFC 5155 specification implies that an algorithm must perform thousands of iterations of a hash function in certain situations.
