I am not aware that the Debian installer writes into the byte range
of the ISO 9660 filesystem.

The ISO 9660 filesystem itself is quite safe from being overwritten.
But MS-Windows or the boot firmware might decide to add files to
the EFI partition which is advertised by the partition table in the
System Area of the ISO filesystem.
