Linux Distros 未修补的漏洞：CVE-2026-14612
medium Nessus 插件 ID 325064
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。- FreeIPA ipa-otpd 后台程序的 OAuth2 设备授权处理程序中的两个差一错误可在处理来自已配置外部 OAuth2/OIDC 身份提供程序的超大响应时造成越界内存访问。能够控制或能够作为中间人的 IdP 端点的攻击者可能会触发 ipa-otpd，使其在超过固定大小缓冲区终点外的一个字节处写入或读取。要利用此漏洞，需要为 FreeIPA 配置外部 IdP、攻击者控制或该 IdP 的 MITM，并且需要用户发起 OAuth2 设备授权流。最可能的影响是影响 ipa-otpd 后台程序的有限拒绝服务。（CVE-2026-14612）
请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。
