Well, I can see at least one bug but it's not security related:

If "Buffer->alloc == X" (but offset == end == 0) and "len == X" then
it allocates an extra "X + 32k" bytes rather than filling the existing
buffer exactly.  That, however wasteful, may be part of the design as
it is hard to judge it alone like that.

Maybe if you can see others you'll highlight them ?
