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

dproxy是Matthew Pratt个人开发者的一个智能缓存 DNS 代理。 dproxy 存在安全漏洞，该漏洞源于其发送给DNS解析器的上游查询中使用静态UDP源端口(仅在启动时随机选择)。这使得DNS缓存中毒，因为没有足够的熵来防止流量注入攻击。

Vulnerability Description
dproxy-nexgen (aka dproxy nexgen) uses a static UDP source port (selected randomly only at boot time) in upstream queries sent to DNS resolvers. This allows DNS cache poisoning because there is not enough entropy to prevent traffic injection attacks.
