patch 9.0.2106: [security]: Use-after-free in win_close() Commit: https://github.com/vim/vim/commit/25aabc2b8ee1e19ced6f4da9d866cf9378fc4c5a Author: Christian Brabandt <cb@256bit.org> Date: Tue Nov 14 19:31:34 2023 +0100 patch 9.0.2106: [security]: Use-after-free in win_close() Problem: [security]: Use-after-free in win_close() Solution: Check window is valid, before accessing it If the current window structure is no longer valid (because a previous autocommand has already freed this window), fail and return before attempting to set win->w_closing variable. Add a test to trigger ASAN in CI Signed-off-by: Christian Brabandt <cb@256bit.org>
