segment of allocated memory is uninitialized (it is not zeroed-out). While
this design makes the allocation of memory quite fast, the allocated segment of
memory might contain old data that is potentially sensitive. Using a
Buffer.allocUnsafe() without completely overwriting the
memory can allow this old data to be leaked when the
Buffer memory is read.
While there are clear performance advantages to using
Buffer.allocUnsafe(), extra care must be taken in order to avoid
introducing security vulnerabilities into an application.
