electron is vulnerable to Heap-based Buffer Overflow
88
High Risk
This Affects:
electronTL;DR
electron's bundled WebRTC audio path can overflow heap buffers when crossfading from comfort-noise or expand frames to normal frames with mismatched vector sizes. Crafted HTML that drives WebRTC audio streams can supply inconsistent frame sizes. Pre-fix builds risk sandboxed memory corruption and code execution. The backport validates vector sizes before performing the crossfade.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
electron is vulnerable to Heap-based Buffer Overflow in versions 40.0.0 - 40.10.2.
