CVE-2016-6351 [MEDIUM] CVE-2016-6351 Qemu: scsi: esp: OOB write access in esp_do_dma
CVE-2016-6351 Qemu: scsi: esp: OOB write access in esp_do_dma
Quick Emulator(Qemu) built with the ESP/NCR53C9x controller emulation support
is vulnerable to an OOB write access issue. It could occur while doing DMA
read into ESP command buffer 's->cmdbuf'; It could write past the 's->cmdbuf'
area, if it was transferring more than 16 bytes in esp_do_dma().
A privileged user inside guest could use this flaw to crash the Qemu process
resulting in DoS OR potentially leverage it to execute arbitrary code with
privileges of the Qemu process on the host.
