Low risk4th percentile - higher than 4% of all known CVEs
Summary
In Electron prior to versions 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5, a vulnerability was found in the clipboard.readImage() function. If the clipboard contains image data that fails to decode, passing a null bitmap to image construction causes a controlled abort and process crash. Only apps calling clipboard.readImage() are affected.
Risk Assessment
The risk involves a denial of service (DoS) via process crash by placing malformed image data in the clipboard. No code execution or memory corruption risk.
Recommendation
It is recommended to upgrade Electron to versions 39.8.5, 40.8.5, 41.1.0, or 42.0.0-alpha.5, which include the fix.
Original NVD description (English source)
Electron is a framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. Prior to 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5, 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. This vulnerability is fixed in 39.8.5, 40.8.5, 41.1.0, and 42.0.0-alpha.5.
