An update that solves 12 vulnerabilities and has four fixes
is now available.

Description:

This update for qemu fixes several issues.

These security issues were fixed:

- CVE-2017-15268: Qemu allowed remote attackers to cause a memory leak by
triggering slow data-channel read operations, related to
io/channel-websock.c (bsc#1062942).
- CVE-2017-9524: The qemu-nbd server when built with the Network Block
Device (NBD) Server support allowed remote attackers to cause a denial
of service (segmentation fault and server crash) by leveraging failure
to ensure that all initialization occurs talking to a client in the
nbd_negotiate function (bsc#1043808).
- 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-2017-10911: 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-2017-10664: 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-2017-14167: 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)

These non-security issues were fixed:

- Fixed not being able to build from rpm sources due to undefined macro
(bsc#1057966)
- Fixed wrong permissions for kvm_stat.1 file
- Fixed KVM lun resize not working as expected on SLES12 SP2 HV
(bsc#1043176)
