Vulnerability Title
bird-lg-go: Fatal Out-of-Memory (OOM) Denial of Service via Unbounded JSON Decoding
Vulnerability Description
bird-lg-go is a BIRD looking glass in Go. Prior to 1.4.5, the apiHandler (and similarly webHandlerTelegramBot) processes user-provided JSON payloads by directly using json.NewDecoder(r.Body).Decode(&request) without restricting the maximum read size. An unauthenticated remote attacker can stream an extremely large, endless JSON payload (e.g., several Gigabytes of padding) over a single TCP connection. Because Go's JSON decoder attempts to allocate memory for the entire parsed structure, this rapidly exhausts the host's physical RAM or container limits, leading to an unrecoverable fatal error: runtime: out of memory. This vulnerability is fixed in 1.4.5.

Vulnerability Title
Bird-lg-go 资源管理错误漏洞
Vulnerability Description
Bird-lg-go是Yuhui Xu个人开发者的一个BGP路由查询工具。 bird-lg-go 1.4.5之前版本存在资源管理错误漏洞,该漏洞源于apiHandler处理用户提供的JSON有效载荷时未限制最大读取大小,可能导致未认证的远程攻击者通过流式传输大量JSON数据导致内存耗尽。
