- CVE-2017-7718: hw/display/cirrus_vga_rop.h allowed local guest OS privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors related to copying VGA data via the cirrus_bitblt_rop_fwd_transp_ and cirrus_bitblt_rop_fwd_ functions (bsc#1034908)

- CVE-2017-7980: An out-of-bounds r/w access issues in the Cirrus CLGD 54xx VGA Emulator support allowed privileged user inside guest to use this flaw to crash the Qemu process resulting in DoS or potentially execute arbitrary code on a host with privileges of Qemu process on the host (bsc#1035406)

- CVE-2017-8112: hw/scsi/vmw_pvscsi.c allowed local guest OS privileged users to cause a denial of service (infinite loop and CPU consumption) via the message ring page count (bsc#1036211)

- CVE-2017-9375: The USB xHCI controller emulator support was vulnerable to an infinite recursive call loop issue, which allowed a privileged user inside guest to crash the Qemu process resulting in DoS (bsc#1042800)

- CVE-2017-9373: The IDE AHCI Emulation support was vulnerable to a host memory leakage issue, which allowed a privileged user inside guest to leak host memory resulting in DoS (bsc#1042801)
