ASAR Integrity bypass via filetype confusion in electron
This only impacts apps that have the `embeddedAsarIntegrityValidation` and `onlyLoadAppFromAsar` [fuses](https://www.electronjs.org/docs/latest/tutorial/fuses) enabled.  Apps without these fuses enabled are not impacted.  This issue is specific to macOS as these fuses are only currently supported on macOS.

Specifically this issue can only be exploited if your app is launched from a filesystem the attacker has write access too.  i.e. the ability to edit files inside the `resources` folder in your app installation on Windows which these fuses are supposed to protect against.

Out-of-bounds Write
Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)

Electron vulnerable to Heap Buffer Overflow in NativeImage
### Impact
The `nativeImage.createFromPath()` and `nativeImage.createFromBuffer()` functions call a function downstream that is vulnerable to a heap buffer overflow. An Electron program that uses either of the affected functions is vulnerable to a buffer overflow if an attacker is in control of the image's height, width, and contents.

### Workaround
There are no app-side workarounds for this issue. You must update your Electron version to be protected.

### Patches

- `v28.3.2`
- `v29.3.3`
- `v30.0.3`
