patch 9.0.2068: [security] overflow in :historyv9.0.2068
Problem: [security] overflow in :history
Solution: Check that value fits into int
The get_list_range() function, used to parse numbers for the :history
and :clist command internally uses long variables to store the numbers.
However function arguments are integer pointers, which can then
overflow.
Check that the return value from the vim_str2nr() function is not larger
than INT_MAX and if yes, bail out with an error. I guess nobody uses a
cmdline/clist history that needs so many entries... (famous last words).
It is only a moderate vulnerability, so impact should be low.
