CVE-2024-46993: 
JavaScript vulnerability analysis and mitigation

Electron, an open source framework for writing cross-platform desktop applications using JavaScript, HTML and CSS, has been found to contain a heap buffer overflow vulnerability (CVE-2024-46993). The vulnerability affects versions prior to 28.3.2, 29.3.3, and 30.0.3, specifically in the nativeImage.createFromPath() and nativeImage.createFromBuffer() functions (GitHub Advisory).

The vulnerability is classified as a heap-based buffer overflow (CWE-122) that occurs when calling downstream functions from nativeImage.createFromPath() and nativeImage.createFromBuffer(). The severity is rated as MODERATE with a CVSS v4.0 score of 4.4. The vulnerability requires local access (AV:L) with high attack complexity (AC:H), low privileges (PR:L), and no user interaction (UI:N). The potential impact on vulnerable systems includes high confidentiality, integrity, and availability risks (VC:H/VI:H/VA:H) (GitHub Advisory).

If successfully exploited, an attacker who has control over an image's height, width, and contents could trigger a buffer overflow in the affected Electron application. This could potentially lead to unauthorized access, data manipulation, or system compromise (GitHub Advisory).

The vulnerability has been patched in Electron versions 28.3.2, 29.3.3, and 30.0.3. There are no alternative workarounds available, and users must update to the patched versions to protect against this vulnerability (GitHub Advisory).
