[原文]The vty layer in Quagga before 0.96.4, and Zebra 0.93b and earlier, does not verify that sub-negotiation is taking place when processing the SE marker, which allows remote attackers to cause a denial of service (crash) via a malformed telnet command to the telnet CLI port, which may trigger a null dereference.


[CNNVD]GNU Zebra / Quagga远程拒绝服务攻击漏洞(CNNVD-200312-062)

        
        Zebra是一款开放源代码TCP/IP路由模拟程序,Quagga实现同样功能。
        GNU Zebra / Quagga不正确处理畸形telnet命令请求,远程攻击者可以利用这个漏洞对服务程序进行拒绝服务攻击。
        攻击者连接GNU Zebra / Quagga的telnet管理端口,发送畸形telnet命令,程序尝试废弃非法NULL指针时而崩溃。

It has been reported that Zebra, as well as Quagga, may be vulnerable to a remote denial of service vulnerability that may allow an attacker to cause the software to crash or hang. The issue is reported to occur if an attacker attempts to connect to the Zebra telnet management port while a password is enabled. The program will crash when attempting to dereference an invalid, possibly NULL, pointer.

All versions of GNU Zebra are said to be vulnerable to this issue. All versions of Quagga prior to 0.96.4 are also vulnerable.
