Electron: Off-screen rendering trusts GPU-supplied geometry over shared-memory size

Quick fix

GHSA-pfmc-3mgc-p6fp — electron: upgrade to the fixed version with the command below.

npm install electron@39.8.10

Details

### Impact In offscreen rendering mode, frame data received from the GPU process was not fully validated by the main process. A compromised GPU process could cause the main process to read out-of-bounds memory while producing `paint` event images, disclosing memory or crashing the app.

Apps are only affected if they use offscreen rendering (`webPreferences.offscreen`) and an attacker has separately gained code execution in the GPU process. Apps that do not use offscreen rendering are not affected.

### Workarounds There are no app side workarounds, you must update to a patched version of Electron.

### Fixed Versions * `42.0.0-beta.3` * `41.2.1` * `40.9.0` * `39.8.10`
