How to fix?

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 Buffer Underflow. Since there may be multiple instance of DWriteFontProxyImpl instantiated for multiple RenderProcessHosts, and DWriteFontProxyImpl::GetUniqueNameLookupTable may access DWriteFontLookupTableBuilder::QueueShareMemoryRegionWhenReady from separate threads, there may be race conditions around the pending_callbacks_ member of DWriteFontLookupTableBuilder.
