Exploitation

Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

ypserv包含网络信息服务(NIS)服务器。 ypserv在处理部分客户端请求时存在问题，远程攻击者可以利用这个漏洞对服务器进行拒绝服务攻击。 如果恶意客户端通过TCP查询ypserv并随后忽略服务器的应答，ypserv会停止尝试发送应答回复，因此就导致ypserv对其他客户端的请求不进行任意应答，产生拒绝服务。 版本2.7及以上版本通过对每个客户端派生一个子进程来防止此问题的出现。
