CVE-2023-4408

一、漏洞信息
 漏洞编号：[CVE-2023-4408](https://nvd.nist.gov/vuln/detail/CVE-2023-4408)
 漏洞归属组件：[bind](https://gitee.com/src-openeuler/bind)
 漏洞归属的版本：9.11.21,9.11.4,9.16.23,9.16.37,9.18.21
 CVSS V3.0分值：
  BaseScore：7.5 High
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  The DNS message parsing code in `named` includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected `named` instance by exploiting this flaw. This issue affects both authoritative servers and recursive resolvers.This issue affects BIND 9 versions 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1, and 9.18.11-S1 through 9.18.21-S1.

二、漏洞分析结构反馈
 影响性分析说明：
  解析大型 DNS 消息可能会导致 CPU 负载过高在named中的DNS消息解析代码中存在一个部分，其计算复杂性过高。虽然对于典型的DNS流量不会造成问题，但是利用这个漏洞，定制的查询和响应可能会对受影响的named实例造成过高的CPU负载。该问题影响权威服务器和递归解析器。此问题影响BIND 9版本9.0.0至9.16.45，9.18.0至9.18.21，9.19.0至9.19.19，9.9.3-S1至9.11.37-S1，9.16.8-S1至9.16.45-S1以及9.18.11-S1至9.18.21-S1。
