   An update that solves 23 vulnerabilities and has four fixes
   is now available.

Description:

   This update for qemu fixes several issues.

   These security issues were fixed:

   - CVE-2017-9330: USB OHCI Emulation in qemu allowed local guest OS users
     to cause a denial of service (infinite loop) by leveraging an incorrect
     return value (bsc#1042159).
   - CVE-2017-8379: Memory leak in the keyboard input event handlers support
     allowed local guest OS privileged users to cause a denial of service
     (host memory consumption) by rapidly generating large keyboard events
     (bsc#1037334).
   - CVE-2017-8309: Memory leak in the audio/audio.c allowed remote attackers
     to cause a denial of service (memory consumption) by repeatedly starting
     and stopping audio capture (bsc#1037242).
   - CVE-2017-7493: The VirtFS, host directory sharing via Plan 9 File
     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-2017-7377: The v9fs_create and v9fs_lcreate functions in
     hw/9pfs/9p.c allowed local guest OS privileged users to cause a denial
     of service (file descriptor or memory consumption) via vectors related
     to an already in-use fid (bsc#1032075).
   - CVE-2017-8086: A memory leak in the v9fs_list_xattr function in
     hw/9pfs/9p-xattr.c allowed local guest OS privileged users to cause a
     denial of service (memory consumption) via vectors involving the
     orig_value variable (bsc#1035950).
   - 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 in hw/usb/hcd-ohci.c
     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 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-2017-9374: Missing free of 's->ipacket', causes a host memory leak,
     allowing for DoS (bsc#1043073).
   - 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).
   - CVE-2017-8380: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation
     support was vulnerable to an out-of-bounds read access issue which
     allowed a privileged user inside guest to read host memory resulting in
     DoS (bsc#1037336).
   - 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-2017-7471: The VirtFS host directory sharing via Plan 9 File
     System(9pfs) support was vulnerable to an improper access control 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#1034866).
   - Fix privilege escalation in TCG mode of QEMU. This is not considered a
     security issue by the upstream project, but is included as additional
     hardening (bsc#1030624)
   - Fix potential DoS in virtfs
   - CVE-2016-10028: The Virtio GPU Device emulator support was vulnerable to
     an out of bounds memory access issue allowing a guest user to crash the
     Qemu process instance on a host, resulting in DoS (bsc#1017084,
     bsc#1016503)
   - CVE-2016-10029: The Virtio GPU Device emulator support was vulnerable to
     an OOB read issue allowing a guest user to crash the Qemu process
     instance resulting in Dos (bsc#1017081, bsc#1016504)
   - 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-2017-9503: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation
     support was vulnerable to a null pointer dereference issue which allowed
     a privileged user inside guest to crash the Qemu process on the host
     resulting in DoS (bsc#1043296).

   This non-security issue was fixed:

   - Enable MONITOR/MWAIT support for guests (bsc#1031142)
