一、漏洞信息
漏洞编号:CVE-2023-4408
漏洞归属组件:bind
漏洞归属的版本:9.11.21,9.11.4,9.16.23,9.16.37,9.18.21,9.18.33
CVSS评分:
BaseScore:7.5 High
Vector:CVSS:3.1/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.

@robertxw 经过 cve-manager 解析, 已分析的内容如下表所示:

状态 需分析 内容
已分析 1.影响性分析说明 为了保持其缓存数据库的高效性,作为递归解析器运行的named进程会周期性地尝试清理数据库。它使用了几种方法,包括一些异步方法:首先分配一小块内存,指向可以清理的缓存元素,然后将其加入队列以便稍后处理。然而,发现如果解析器持续处理触发这种类型缓存数据库维护的查询模式,named可能无法及时处理清理事件。这反过来会导致待清理事件列表随时间无限增长,从而显著超出配置的max-cache-size限制。此问题影响BIND 9版本9.16.0至9.16.45和9.16.8-S1至9.16.45-S1。

状态 分析项目 内容
已分析 1.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。
