公告摘要：krb5安全漏洞
等級：重要
發布日期：2023-12-28
詳細介紹
1. 修復的CVE
CVE-2022-42898
MIT Kerberos是一個用于在網絡集群中進行身份驗證的軟件。Kerberos 同時作為一種網絡認證協議，其設計目標是通過密鑰系統為客戶機 / 服務器應用程序提供強大的認證服務。 1.19.4之前的MIT Kerberos 5（又名krb5）和1.20.1之前的1.20.x中的PAC解析存在整數溢出，這可能導致32位平臺上的遠程代碼執行，并導致其他平臺上的拒絕服務。
CVE-2018-20217
MIT krb5（又名MIT Kerberos 5）是一套網絡認證協議，它采用客戶端/服務器結構，并且客戶端和服務器端均可對對方進行身份認證（即雙重驗證），可防止竊聽、防止replay攻擊等。 MIT Kerberos 5 1.17之前版本中的KDC存在輸入驗證錯誤漏洞。攻擊者可通過發送S4U2Self請求利用該漏洞造成KDC崩潰。

4. 修復方法
方法一：升級安裝
執行更新命令進行升級
$sudo apt update
$sudo apt install libkdb5-9
$sudo apt install krb5-user
$sudo apt install libgssapi-krb5-2
$sudo apt install krb5-kdc
$sudo apt install krb5-admin-server
方法二：下載軟件包進行升級安裝
通過軟件包地址下載軟件包，使用軟件包升級命令根據受影響的軟件包列表升級相關的組件包。
$sudo dpkg -i /Path1/Package1 /Path2/Package2 /Path3/Package3……
注：Path 指軟件包下載到本地的路徑，Package指下載的軟件包名稱，多個軟件包則以空格分開。
