CVE-2022-3324

A stack-based buffer overflow vulnerability was found in Vim's win_redr_ruler() function of the src/drawscreen.c file. The issue occurs when using a negative array index with a negative width window. This flaw allows an attacker to trick a user into opening a specially crafted file, which triggers the bug, causing an application to crash, possibly executing code and corrupting memory.

Red Hat Product Security has rated this issue as having a Low security impact, because the "victim" has to run an untrusted file IN SCRIPT MODE. Someone who is running untrusted files in script mode is equivalent to someone just taking a random python script and running it.
