These security issues were fixed:
- CVE-2017-15289: The mode4and5 write functions allowed local OS guest
 privileged users to cause a denial of service (out-of-bounds write
 access and Qemu process crash) via vectors related to dst calculation
 (bsc#1063122)
- CVE-2017-2633: The VNC display driver support was vulnerable to an
 out-of-bounds memory access issue. A user/process inside guest could use
 this flaw to cause DoS (bsc#1026612)
- CVE-2017-15038: Race condition in the v9fs_xattrwalk function local
 guest OS users to obtain sensitive information from host heap memory via
 vectors related to reading extended attributes (bsc#1062069)
- CVE-2017-14167: Integer overflow in the load_multiboot function allowed
 local guest OS users to execute arbitrary code on the host via crafted
 multiboot header address values, which trigger an out-of-bounds write
 (bsc#1057585)
- CVE-2017-11434: The dhcp_decode function in slirp/bootp.c allowed local
 guest OS users to cause a denial of service (out-of-bounds read) via a
 crafted DHCP options string (bsc#1049381)
- CVE-2017-11334: The address_space_write_continue function allowed local
 guest OS privileged users to cause a denial of service (out-of-bounds
 access and guest instance crash) by leveraging use of qemu_map_ram_ptr
 to access guest ram block area (bsc#1048902)
- CVE-2017-13672: The VGA display emulator support allowed local guest OS
 privileged users to cause a denial of service (out-of-bounds read and
 QEMU process crash) via vectors involving display update (bsc#1056334)
- CVE-2017-5973: A infinite loop while doing control transfer in
 xhci_kick_epctx allowed privileged user inside the guest to crash the
 host process resulting in DoS (bsc#1025109)
- CVE-2017-5987: The sdhci_sdma_transfer_multi_blocks function in
 hw/sd/sdhci.c allowed local OS guest privileged users to cause a denial
 of service (infinite loop and QEMU process crash) via vectors involving
 the transfer mode register during multi block transfer (bsc#1025311)
- CVE-2017-6505: The ohci_service_ed_list function allowed local guest OS
 users to cause a denial of service (infinite loop) via vectors involving
 the number of link endpoint list descriptors (bsc#1028184)
- CVE-2016-9603: A privileged user within the guest VM could have caused a
 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 ... [Please see the references for more information on the vulnerabilities]");
