A heap-based buffer overflow was found in QEMU through 5.0.0 in the SDHCI
device emulation support. It could occur while doing a multi block SDMA
transfer via the sdhci_sdma_transfer_multi_blocks() routine in
hw/sd/sdhci.c. A guest user or process could use this flaw to crash the
QEMU process on the host, resulting in a denial of service condition, or
potentially execute arbitrary code with privileges of the QEMU process on
the host.
