Description Prasad Pandit 2017-01-30 09:36:43 UTC 
Quick emulator(Qemu) built with the SDHCI device emulation support is vulnerable
to an OOB heap access issue. It could occur while doing a multi block SDMA
transfer via sdhci_sdma_transfer_multi_blocks routine.

A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS or potentially execute arbitrary code with privileges of the
Qemu process on the host.
