mysql Node.JS Module Vulnerable to Remote Memory Exposure

Versions of mysql before 2.14.0 are vulnerable to remove memory exposure.

Affected versions of mysql package allocate and send an uninitialized memory over the network when a number is provided as a password.

Only mysql running on Node.js versions below 6.0.0 are affected due to a throw added in newer node.js versions.

Proof of Concept:

require('mysql').createConnection({
  host: 'localhost',
  user: 'user',
  password : USERPROVIDEDINPUT,  // number
  database : 'my_db'
}).connect();

Recommendation

Update to version 2.14.0 or later.
