electron is vulnerable to Out-of-Bounds Read
43
Medium Risk
This Affects:
electronTL;DR
electron's embedded ANGLE Metal GPU path on macOS can read outside intended buffer bounds when sizing compressed texture uploads. Crafted HTML that drives GPU texture operations can reach the faulty pitch computation. Pre-fix builds may leak adjacent memory contents from the GPU process. The backport rounds buffer sizes safely for compressed texture PBO handling.
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.
