1.修復的漏洞 ·CVE-2024-3596 描述：RADIUS（遠程認證撥號用戶服務）協議中的一個漏洞允許攻擊者偽造認證響應，當消息認證器（Message-Authenticator）屬性未被強制執行時。此問題源于使用 MD5 進行的加密安全性檢查不可靠，使攻擊者能夠偽造基于 UDP 的 RADIUS 響應包。這可能導致通過將 Access-Reject 響應修改為 Access-Accept 響應，從而繞過認證過程，獲得未經授權的訪問權限。 2.受影響的軟件包 ·中標麒麟高級服務器操作系統 V7 ·aarch64架構: krb5-server-ldap、krb5-libs、libkadm5、krb5-devel、krb5-server、krb5-pkinit、krb5-workstation ·x86_64架構:
