patch 9.0.2109: [security]: overflow in nv_z_get_count Commit: https://github.com/vim/vim/commit/58f9befca1fa172068effad7f2ea5a9d6a7b0cca Author: Christian Brabandt <cb@256bit.org> Date: Tue Nov 14 21:02:30 2023 +0100 patch 9.0.2109: [security]: overflow in nv_z_get_count Problem: [security]: overflow in nv_z_get_count Solution: break out, if count is too large When getting the count for a normal z command, it may overflow for large counts given. So verify, that we can safely store the result in a long. Signed-off-by: Christian Brabandt <cb@256bit.org>
