Description Adam Mariš 2016-06-07 09:06:36 UTC 
There was a missing check for negative parameter value in Buffer() and Buffer.allocUnsafe(). When user input is passed unchecked to the Buffer constructor or allocUnsafe(), it can expose parts of the memory slab used by other Buffers in the application.
