[原文]MIT Kerberos V5 Key Distribution Center (KDC) before 1.2.5 allows remote authenticated attackers to cause a denial of service (crash) on KDCs within the same realm via a certain protocol request that causes a null dereference.


[CNNVD]Kerberos密钥分发中心远程拒绝服务攻击漏洞(CNNVD-200302-029)

        
        Kerberos是一款广泛使用的使用强壮的加密来验证客户端和服务器端的网络协议。
        MIT Kerberos密钥分发中心(Key Distribution Center)对部分恶意'Ticket'授权服务请求处理不正确,远程攻击者可以利用这个漏洞对KDC进行拒绝服务攻击。
        在验证后部分特殊针对KDC的请求可导致KDC废弃NULL指针而崩溃,此漏洞在KDC不正确配置的情况下更容易产生。恶意远程或本地用户可以杀掉KDC服务程序krb5kdc(1M)或任何Kerberos应用程序,如/usr/krb5/lib的telnetd(1M)、rlogind(1M)和rshd(1M)程序。
        漏洞是由于Kerberos协议在处理TGS-REQ交换时产生,此请求只有在验证之后才能进行,因此在一定程度上降低了漏洞威胁,不过攻击者可以通过猜测密码访问KDC而进行此拒绝服务攻击。

- 漏洞讨论

A vulnerability has been discovered in Kerberos Key Distribution Center (KDC). It has been reported that a denial of service can be triggered through a malicious Ticket Granting Service request. An authenticated malicious attacker could exploit this issue remotely to cause to dereference a NULL pointer. This would result in the affected KDC service to crash. Multiple KDC services may also crash.

This issue has been reported to affect Kerberos Key Distribution Center versions prior to 1.2.5.
