GMS-2019-136: Remote Memory Exposure in mysql

Versions of mysql before 2.14.0 is 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 is 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.
