  "title": "Notepad\u002B\u002B: Authenticode verification bypass allows modified updater execution",
  "description": "Notepad\u002B\u002B is a free and open-source source code editor. From 8.9.7 until 8.9.8, the Notepad\u002B\u002B updater and signature verification path can accept a modified GUP.exe file whose embedded certificate metadata remains present even though its Authenticode digest is invalid. An attacker who can replace or plant the updater-related file can cause Notepad\u002B\u002B to launch attacker-modified code when a user triggers the updater path, but the issue does not provide remote code execution by itself. This issue is fixed in version 8.9.8.",
