Mitigation checklist
Recommended fix / mitigation
- Users are advised to avoid opening or processing undo files from untrusted or unknown sources. If your team compiles Vim from source, ensure standard compiler security flags (like -D_FORTIFY_SOURCE=2 or 3) are enabled. This provides a safety net by detecting out-of-bounds reads and safely terminating the application before exploitation can occur.
