CVE-2023-43637 (eve)

Due to the implementation of "deriveVaultKey", prior to version 7.10, the generated vault key
would always have the last 16 bytes predetermined to be "arfoobarfoobarfo".

This issue happens because "deriveVaultKey" calls "retrieveCloudKey" (which will always
return "foobarfoobarfoobarfoobarfoobarfo" as the key), and then merges the 32byte
randomly generated key with this key (by takeing 16bytes from each, see "mergeKeys").

This makes the key a lot weaker.

This issue does not persist in devices that were initialized on/after version 7.10, but devices …
