MIT Kerberos 5 ‘kdb_ldap’ 插件拒绝服务漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
MIT Kerberos 5（又名krb5）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 (也称为krb5) 1.9至1.9.1版本中Key Distribution Center (KDC)中的kdb_ldap插件当使用LDAP后端时存在漏洞。远程攻击者可借助对realm的不正确字符串的kinit操作导致拒绝服务（空指针解引用和守护进程崩溃）。
