Subject: [FD] [Samba 3.0.37] EnumPrinters memory corruption

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.

(looking for remote work as programmer, if in need, email me at
g.avosani@...il.com (PHP, Perl, C/C++, Java and more))

Download attachment "enumprinters.tgz" of type "application/x-gzip" (15215 bytes)
