electron is vulnerable to Out-of-Bounds Read
65
Medium Risk
This Affects:
electronTL;DR
electron's embedded ANGLE Metal GPU path on macOS can compute incorrect pitch for compressed textures in pixel-buffer uploads. Crafted pages that drive compressed texture transfers can read beyond allocated buffers. Pre-fix versions may disclose sensitive GPU process memory. The backport corrects pitch computation for compressed texture PBO operations.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and ship electron desktop apps on macOS.
Background info
electron is vulnerable to Out-of-Bounds Read in versions 40.0.0 - 40.10.2 and 41.0.0 - 41.7.1.
