[原文]Domain Name Relay Daemon (dnrd) 2.10 and earlier allows remote malicious DNS sites to cause a denial of service and possibly execute arbitrary code via a long or malformed DNS reply, which is not handled properly by parse_query, get_objectname, and possibly other functions.


[CNNVD]dnrd DNS请求远程拒绝服务攻击漏洞(CNNVD-200203-082)

        
        Dnrd是一个代理DNS请求的守护进程,它适用于需要多个ISP支持的家庭网络。它可以转发所有DNS请求到相应ISP的DNS服务器。
        Dnrd 2.10存在设计问题,远程攻击者可以对服务器程序实施拒绝服务攻击。
        通过向dnrd进程发送随机的数据流,会导致服务器进程崩溃。这是由于parse_query、get_objectname函数(或其他函数)没有正确进行边界检查引起的。利用这个问题,攻击者也有可能在主机上执行任意指令。

DNRD 1.x/2.x DNS Request/Reply Denial Of Service Vulnerability (EDBID:21236)

dnrd (Domain Name Relay Daemon) is a freely available, open-source proxy name server. It will run on a number of Unix and Linux distributions.

There is a lack of sufficient bounds checking in DNS request and reply functions. As a result, it is possible for a remote attacker to cause a denial of service to legitimate users of dnrd.

It is not known whether it is possible to execute arbitrary attacker-supplied instructions as a result of this vulnerability.
