Node.js third-party modules: `base64url` allocates uninitialized Buffers when number is passed in input on Node.js 4.x and below

I would like to report an uninitialized Buffer allocation issue in base64url. It allows to extract sensitive data from uninitialized memory or to cause a DoS by passing in a large number, in setups where typed user input can be passed e.g. from JSON, on Node.js 4.x and lower. Module module name:...

Node.js third-party modules: `npmconf` (and `npm` js api) allocate and write to disk uninitialized memory content when a typed number is passed as input on Node.js 4.x

I would like to report a Buffer allocation issue in npmconf and npm package js api. It allows to extract sensitive content from uninitialized memory by passing typed input to setCredentialsByURI, limited to Node.js 4.x and below. Module module name: npmconf version: 2.1.2 npm page:...

Node.js third-party modules: `memjs` allocates and stores buffers on typed input, resulting in DoS and uninitialized memory usage

I would like to report a Buffer allocation vulnerability in memjs. In cases when the attacker is able to pass typed input e.g. via JSON to the storage, it allows to cause DoS on all Node.js versions and to store and potentially later extract chunks of uninitialized server memory containing...

Node.js third-party modules: `https-proxy-agent` passes unsanitized options to Buffer(arg), resulting in DoS and uninitialized memory leak

I would like to report a Buffer allocation vulnerability in https-proxy-agent. In setups where auth argument is user-controlled, it allows to: 1. cause Denial of Service by trivially consuming all the available CPU resources 2. extract uninitialized memory chunks from the server on Node.js This...
