dependabot[bot] opened a new pull request, #4662: URL: https://github.com/apache/zeppelin/pull/4662
Bumps [ws](https://github.com/websockets/ws) to 1.1.5 and updates ancestor dependency [angular-websocket](https://github.com/angular-class/angular-websocket). These dependencies need to be updated together. Updates `ws` from 0.7.2 to 1.1.5 <details> <summary>Release notes</summary> <p><em>Sourced from <a href="https://github.com/websockets/ws/releases";>ws's releases</a>.</em></p> <blockquote> <h2>1.1.5</h2> <h1>Bug fixes</h1> <ul> <li>Fixed a DoS vulnerability (f8fdcd4).</li> </ul> <h2>1.1.4</h2> <h1>Notable changes</h1> <ul> <li>Removed istanbul coverage folder from npm package (fac50ac).</li> </ul> <h2>1.1.3</h2> <h1>Notable changes</h1> <ul> <li>Added support for <code>bufferutil@>1</code> and <code>utf-8-validate@>2</code> (b4cf110).</li> </ul> <h2>1.1.2</h2> <h1>Bug fixes</h1> <ul> <li>The masking key is now generated using <code>crypto.randomBytes()</code> instead of <code>Math.random()</code> (<a href="https://redirect.github.com/websockets/ws/issues/994";>#994</a>).</li> <li>Fixed an issue that could cause a stack overflow crash (c1f3b21).</li> </ul> <h2>1.1.1</h2> <p><a href="https://github.com/websockets/ws/compare/1.1.0...1.1.1";>https://github.com/websockets/ws/compare/1.1.0...1.1.1</a></p> <h2>1.1.0</h2> <p><a href="https://github.com/websockets/ws/compare/1.0.1...1.1.0";>https://github.com/websockets/ws/compare/1.0.1...1.1.0</a></p> <h2>Buffer vulnerability</h2> <p>There has been vulnerability in the ping functionality of the <code>ws</code> module which allowed clients to allocate memory by simply sending a ping frame. The ping functionality by default responds with a pong frame and the previously given payload of the ping frame. This is exactly what you expect, but internally we always transform all data that we need to send to a <code>Buffer</code> instance and this is where the problem was. We didn't do any checks for the type of data we were sending. With buffers in node when you allocate it when a number instead of a string it will allocate the amount of bytes.</p> <pre lang="js"><code>var x = new Buffer(100); // vs var x = new Buffer('100'); </code></pre> <p>This would allocate 100 bytes of memory in the first example and just 3 bytes with <code>100</code> as value in the second example. So when the server would receive a ping message of <code>1000</code> it would allocate 1000 bytes on the server and returned non-zeroed buffer to the client instead of the actual <code>100</code> message.</p> <pre lang="js"><code>var ws = require('ws') <p>var server = new ws.Server({ port: 9000 }) var client = new ws('ws://localhost:9000')</p> <p>client.on('open', function () { console.log('open') client.ping(50) // this makes the server return a non-zeroed buffer of 50 bytes</p> <p>client.on('pong', function (data) { console.log('got pong') </tr></table> </code></pre></p> </blockquote> <p>...
