______________________________________________________________________________

 

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.
