1. 修复的CVE CVE-2022-42898 MIT Kerberos是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。 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。 CVE-2018-20217 MIT krb5（又名MIT Kerberos 5）是一套网络认证协议，它采用客户端/服务器结构，并且客户端和服务器端均可对对方进行身份认证（即双重验证），可防止窃听、防止replay攻击等。 MIT Kerberos 5 1.17之前版本中的KDC存在输入验证错误漏洞。攻击者可通过发送S4U2Self请求利用该漏洞造成KDC崩溃。 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：
