Linux Distros 未修补的漏洞：CVE-2026-3012
medium Nessus 插件 ID 317041
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。- 在 Samba 的证书自动注册群组策略处理中发现一个缺陷。当启用证书自动注册时，Samba 可能会在未加密的 HTTP 连接上检索 CA 证书，并在未进行正确验证的情况下将其安装到本地信任存储中。可拦截或重定向网络流量的攻击者可利用此行为提供恶意证书颁发机构证书，从而可能允许拦截或欺骗受信任的通信。（CVE-2026-3012）
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
