heap overflow in the device model process, potentially escalating their
privileges to that of the device model process (bsc#1028656)
- 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)

System(9pfs) support, was vulnerable to an improper access control
issue. It could occur while accessing virtfs metadata files in
mapped-file security mode. A guest user could have used this flaw to
escalate their privileges inside guest (bsc#1039495)
- CVE-2016-9602: The VirtFS host directory sharing via Plan 9 File
