These security issues were fixed:
- CVE-2017-10911: The make_response function in the Linux kernel allowed
 guest OS users to obtain sensitive information from host OS (or other
 guest OS) kernel memory by leveraging the copying of uninitialized
 padding fields in Xen block-interface response structures (bsc#1057378).
- CVE-2017-12809: The IDE disk and CD/DVD-ROM Emulator support allowed
 local guest OS privileged users to cause a denial of service (NULL
 pointer dereference and QEMU process crash) by flushing an empty CDROM
 device drive (bsc#1054724).
- 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-2017-15038: 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
