MIT Kerberos 5管理库libkadm5srv远程堆溢出漏洞
Vulnerability Description
Kerberos是美国麻省理工学院（MIT）开发的一套网络认证协议，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管理库在密码历史处理代码中存在一个堆溢出，远程攻击者可以利用这个漏洞以进程权限执行任意指令。 溢出发生在'src/lib/kadm5/srv/svr_principal.c'中的add_to_history()函数中，密码历史存储在一个缓冲区中，即adb->old_keys指向的osa_pw
