[Samba] [Samba 3.0.37] EnumPrinters memory consumption

[Gabriele Avosani]

Hello, i discovered a bug in EnumPrinters.
It seems that it allocates many mega of memory, corrupting memory and
taking control of a memcpy in parse_prs.c:398

It leads to memory corruption, fatal (and fast) exhaustion of resources
and, probably, remote code execution.

I attach a file that can be used as a proof of concept.
