Vulnerability Title
Coturn: Pre-authentication heap memory disclosure in ACME redirect (`try_acme_redirect`)
Vulnerability Description
Coturn is a free open source implementation of TURN and STUN Server. From 4.5.2 through 4.14.0, when Coturn is started with --acme-redirect <URL> and exposes a plaintext-TCP listener, an unauthenticated remote client can send a single ordinary HTTP GET request and receive a 301 response whose Location header contains up to ~870 bytes of adjacent process heap memory. The leaked region is a recycled network receive buffer that is reused without being zeroed, so on a busy server it can contain data from other clients' requests (TURN credentials, OAuth tokens, relayed payloads). Root cause is a signed→unsigned conversion. This issue is fixed in version 4.15.0.

Vulnerability Title
Coturn 缓冲区错误漏洞
Vulnerability Description
Coturn是Coturn组织开源的一款TURN(VoIP媒体业务NAT穿越服务器和网关)和STUN(用户数据报协议简单穿越网络地址转换器)Server的开源实现。 Coturn 4.5.2版本至4.14.0版本存在安全漏洞,该漏洞源于有符号到无符号转换错误,可能导致未经身份验证的远程客户端发送单个HTTP GET请求,获取包含相邻进程堆内存的301响应,泄漏回收未清零的网络接收缓冲区中的敏感数据(如TURN凭据、OAuth令牌)。
