Описание

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.

A flaw was found in the compression Node.js and Express middleware. A remote unauthenticated attacker can exploit this vulnerability by repeatedly initiating and then prematurely aborting connections while compressed responses are being sent. This action prevents the zlib stream, used for compression, from being properly destroyed, leading to a memory leak. Over time, this memory exhaustion can cause the server to crash, resulting in a Denial of Service (DoS).
