patch 9.0.2068: [security] overflow in :history Commit: https://github.com/vim/vim/commit/9198c1f2b1ddecde22af918541e0de2a32f0f45a Author: Christian Brabandt <cb@256bit.org> Date: Thu Oct 26 21:29:32 2023 +0200 patch 9.0.2068: [security] overflow in :history 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.
