CVE-2024-46993
GHSA-6r2x-8pq8-9489
Lifecycle Timeline
3Description
Electron is an open source framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. In versions prior to 28.3.2, 29.3.3, and 30.0.3, the nativeImage.createFromPath() and nativeImage.createFromBuffer() functions call a function downstream that is vulnerable to a heap buffer overflow. An Electron program that uses either of the affected functions is vulnerable to a buffer overflow if an attacker is in control of the image's height, width, and contents. This issue has been patched in versions 28.3.2, 29.3.3, and 30.0.3. There are no workarounds for this issue.

Technical Context
A buffer overflow occurs when data written to a buffer exceeds its allocated size, potentially overwriting adjacent memory and corrupting program state. This vulnerability is classified as Heap-based Buffer Overflow (CWE-122).
Remediation
Use memory-safe languages or bounds-checked functions. Enable ASLR, DEP/NX, and stack canaries. Apply vendor patches promptly.
