Merge remote-tracking branch 'remotes/philmd-gitlab/tags/sdcard-CVE-2020-13253-pull-request' into staging
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.
