______________________________________________________________________________

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)

This update was imported from the SUSE:SLE-12-SP2:Update update project.
