Electron: Crash in clipboard.readImage() on malformed clipboard image data

發布日:2026/4/7修改日:2026/4/8

描述

### Impact Apps that call `clipboard.readImage()` may be vulnerable to a denial of service. If the system clipboard contains image data that fails to decode, the resulting null bitmap is passed unchecked to image construction, triggering a controlled abort and crashing the process. Apps are only affected if they call `clipboard.readImage()`. Apps that do not read images from the clipboard are not affected. This issue does not allow memory corruption or code execution. ### Workarounds Validate that the clipboard contains image data via `clipboard.availableFormats()` before calling `clipboard.readImage()`. Note this only narrows the window — upgrading to a fixed version is recommended. ### Fixed Versions * `42.0.0-alpha.5` * `41.1.0` * `40.8.5` * `39.8.5` ### For more information If you have any questions or comments about this advisory, email us at [[email protected]](mailto:[email protected])
