1. 修復的CVE CVE-2022-42898 MIT Kerberos是美國麻省理工學院（MIT）的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。MIT Kerberos 存在安全漏洞。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。7.7.1之前的Heimdal有“類似的錯誤”。 CVE-2022-44640 Heimdal是Heimdal開源的一個 Kerberos 的實現及安全程序。Heimdal KDC 存在安全漏洞，該漏洞源于ASN.1 編解碼器中的無效自由，攻擊者利用該漏洞可以使用 Kerberos 進行身份驗證可以模擬客戶端或服務，規避驗證。 CVE-2021-44758 Heimdal是Heimdal開源的一個 Kerberos 的實現及安全程序。Heimdal存在安全漏洞，該漏洞源于SPNEGO接受器中的NULL取消引用，導致DoS。 CVE-2022-3437 Dell PowerEdge Server BIOS是美國戴爾（Dell）公司的戴爾（Dell）的一款系統更新驅動程序。Dell PowerEdge Server BIOS 存在安全漏洞，該漏洞源于對用戶輸入驗證不正確。 2. 受影響的操作系統及軟件包 ·銀河麒麟桌面操作系統V10 SP1 x86_64 架構：
