These security issues were fixed:
- CVE-2016-9602: The VirtFS host directory sharing via Plan 9 File
 System(9pfs) support was vulnerable to an improper link following issue
 which allowed a privileged user inside guest to access host file system
 beyond the shared folder and potentially escalating their privileges on
 a host (bsc#1020427)
- 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-2017-10664: qemu-nbd did not ignore SIGPIPE, which allowed remote
 attackers to cause a denial of service (daemon crash) by disconnecting
 during a server-to-client reply attempt (bsc#1046636)
- CVE-2017-10806: Stack-based buffer overflow allowed local guest OS users
 to cause a denial of service (QEMU process crash) via vectors related to
 logging debug messages (bsc#1047674).
- 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-2017-11434: 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-2017-13672: 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-2017-14167: 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-2017-15038: 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-2017-15289: 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-2017-5579: The 16550A UART serial device emulation support was
 vulnerable to a memory leakage issue allowing a privileged user to cause
 a DoS and/or potentially crash the Qemu process on the host (bsc#1021741)
- 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-2017-6505: 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 ... [Please see the references for more information on the vulnerabilities]");
