Vulnerability Title
compression vulnerable to Denial of Service via memory leak on premature response close
Vulnerability Description
compression is a Node.js and Express compression middleware. In versions before 1.8.2, when a client aborts the connection while a compressed response is still being sent, the zlib stream created to compress that response is never destroyed, so each aborted compressed response leaks its native zlib memory. A remote unauthenticated attacker can repeatedly open requests and disconnect early, exhausting the available memory and crashing the server. All applications using compression are affected. The issue is fixed in compression 1.8.2, and users should upgrade to 1.8.2 or later.

Vulnerability Title
expressjs compression 资源管理错误漏洞
Vulnerability Description
expressjs compression是expressjs组织的一款对HTTP响应内容进行压缩的中间件软件。 expressjs compression 1.8.2之前版本存在资源管理错误漏洞,该漏洞源于客户端在压缩响应发送过程中中止连接时,用于压缩响应的zlib流未被销毁,导致每次中止的压缩响应都会泄漏其原生zlib内存,远程未认证攻击者可反复发起请求并提前断开连接,耗尽可用内存并导致服务器崩溃。
