Details

As written in the advisory (Markdown source, shown as plain text).

### Impact Frame data received from the GPU process for `webContents.beginFrameSubscription` 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 the captured frame images, disclosing memory or crashing the app. Apps are only affected if they use `webContents.beginFrameSubscription` and an attacker has separately gained code execution in the GPU process. Apps that do not subscribe to captured frames are not affected. ### Workarounds There are no app side workarounds, you must update to a patched version of Electron. ### Fixed Versions * `45.0.0-alpha.9` * `44.4.3` * `43.7.3` * `42.11.6` ### For more information If you have any questions or comments about this advisory, email us at [[email protected]](mailto:[email protected])
