CVE-2023-23298

The `Toybox.Graphics.BufferedBitmap.initialize` API method in CIQ API version 2.3.0 through 4.1.7 does not validate its parameters, which can result in integer overflows when allocating the underlying bitmap buffer. A malicious application could call the API method with specially crafted parameters and hijack the execution of the device's firmware.
