Upgrade Debian:12

NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu
package and not the qemu
package as distributed by Debian
.
See How to fix?
for Debian:12
relevant fixed versions and status.
hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.
