Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Out-of-bounds Read in the paint event image generation process when offscreen rendering is enabled. An attacker can cause memory disclosure or application crash by compromising the GPU process and sending malicious frame data to the main process.

Note: This is only exploitable if offscreen rendering (webPreferences.offscreen) is enabled and the attacker has already achieved code execution in the GPU process.
