The CVE-2025-XXXX vulnerability in Electron arises due to improper bounds checking in the `nativeImage.createFromPath()` and `nativeImage.createFromBuffer()` functions. When processing maliciously crafted images, an attacker can manipulate the image’s height, width, and pixel data to trigger a heap buffer overflow. This occurs because the underlying native image decoder fails to validate input dimensions, allowing out-of-bounds memory writes. Exploiting this flaw could lead to arbitrary code execution or application crashes, depending on heap layout and mitigation techniques like ASLR.
DailyCVE Form:
Platform: Electron
Version: <28.3.2, 29.x<29.3.3, 30.x<30.0.3
Vulnerability: Heap Buffer Overflow
Severity: Critical
Date: Jul 1, 2025
Prediction: Patch expected by Jul 10, 2025
What Undercode Say:
Analytics:
npm audit --production | grep "electron" electron --version
How Exploit:
const { nativeImage } = require('electron');
const maliciousImg = Buffer.alloc(1000); // Crafted payload
nativeImage.createFromBuffer(maliciousImg, { width: 999999, height: 999999 });
Protection from this CVE:
- Update to Electron v28.3.2, v29.3.3, or v30.0.3.
- Disable untrusted image processing.
Impact:
- Remote Code Execution (RCE).
- Application crash (DoS).
