Thanks for the review.

I do not know where you looked at our code, but in our official git 
repositories for vncterm[1] and spiceterm[2]

those issues are already fixed (since 2017-05-05)

i changed those variables all to unsigned int, which makes those 
increments defined behavior, and the range checks are ok, because
they cannot be negative anymore.
(it may behave strange, but you cannot trigger an out-of-bounds 
read/write anymore)
also, i replaced the vt->cy += buf code paths with calls to
vncterm_gotoxy (which as you mentioned, perform all necessary checks)
