hw/sd/sdcard: Do not switch to ReceivingData if address is invalid (2020-07=
-14 15:46:14 +0200)
----------------------------------------------------------------
Fix CVE-2020-13253
By using invalidated address, guest can do out-of-bounds accesses.
These patches fix the issue by only allowing SD card image sizes
power of 2, and not switching to SEND_DATA state when the address
is invalid (out of range).
This issue was found using QEMU fuzzing mode (using --enable-fuzzing,
see docs/devel/fuzzing.txt) and reported by Alexander Bulekov.
