Linux Distros 未修补的漏洞：CVE-2026-27145
high Nessus 插件 ID 318379
语言：
简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- （*x509。Certificate）。VerifyHostname 之前在对所有 DNS 主题备用名称 （SAN） 条目进行循环中调用 matchHostnames。这会造成字符串。Split（host， .） 可在同一输入主机名上重复执行。对于大型 DNS SAN 列表，验证成本会根据 SAN 条目数乘以主机名的标签计数进行二次方扩展。因为 x509.验证在构建证书链之前验证主机名，此开销即使对于不受信任的证书也会发生。（CVE-2026-27145）
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
