CVE-2023-23300

The `Toybox.Cryptography.Cipher.initialize` API method in CIQ API version 3.0.0 through 4.1.7 does not validate its parameters, which can result in buffer overflows when copying data. A malicious application could call the API method with specially crafted parameters and hijack the execution of the device's firmware.
