Vulnerability Description
In Contiki 3.0, Telnet option negotiation is mishandled. During negotiation between a server and a client, the server may fail to give the WILL/WONT or DO/DONT response for DO and WILL commands because of improper handling of exception condition, which leads to property violations and denial of service. Specifically, a server sometimes sends no response, because a fixed buffer space is available for all responses and that space may have been exhausted.

Vulnerability Description
Contiki是一套用于IoT（物联网）设备的开源跨平台操作系统。 Contiki-os Contiki 存在代码问题漏洞，该漏洞源于 Contiki 3.0 中，Telnet 选项协商处理不当。服务器和客户端在协商过程中，可能会因为异常条件处理不当，导致服务器对DO和WILL命令无法给出WILL/WONT或DO/DONT响应，从而导致属性违规和拒绝服务。 具体来说，服务器有时不发送响应，因为固定的缓冲区空间可用于所有响应，而该空间可能已耗尽。
