1. 修复的CVE CVE-2022-42898 MIT Kerberos是美国麻省理工学院（MIT）的一个用于在网络集群中进行身份验证的软件。Kerberos 同时作为一种网络认证协议，其设计目标是通过密钥系统为客户机 / 服务器应用程序提供强大的认证服务。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解析存在整数溢出，这可能导致32位平台上的远程代码执行，并导致其他平台上的拒绝服务。7.7.1之前的Heimdal有“类似的错误”。 CVE-2022-44640 Heimdal是Heimdal开源的一个 Kerberos 的实现及安全程序。Heimdal KDC 存在安全漏洞，该漏洞源于ASN.1 编解码器中的无效自由，攻击者利用该漏洞可以使用 Kerberos 进行身份验证可以模拟客户端或服务，规避验证。 CVE-2021-44758 Heimdal是Heimdal开源的一个 Kerberos 的实现及安全程序。Heimdal存在安全漏洞，该漏洞源于SPNEGO接受器中的NULL取消引用，导致DoS。 CVE-2022-3437 Dell PowerEdge Server BIOS是美国戴尔（Dell）公司的戴尔（Dell）的一款系统更新驱动程序。Dell PowerEdge Server BIOS 存在安全漏洞，该漏洞源于对用户输入验证不正确。 2. 受影响的操作系统及软件包 ·银河麒麟桌面操作系统V10 SP1 x86_64 架构：
