An update that solves 13 vulnerabilities and has two fixes

is now available.

 

Description:

 

 

qemu was updated to fix several issues.

 

These security issues were fixed:

 

- CVE-2016-9102: Memory leak in the v9fs_xattrcreate function in

hw/9pfs/9p.c in allowed local guest OS administrators to cause a denial

of service (memory consumption and QEMU process crash) via a large

number of Txattrcreate messages with the same fid number (bsc#1014256).

- CVE-2016-9103: The v9fs_xattrcreate function in hw/9pfs/9p.c in allowed

local guest OS administrators to obtain sensitive host heap memory

information by reading xattribute values writing to them (bsc#1007454).

- CVE-2016-9381: Improper processing of shared rings allowing guest

administrators take over the qemu process, elevating their privilege to

that of the qemu process (bsc#1009109)

- CVE-2016-9776: The ColdFire Fast Ethernet Controller emulator support

was vulnerable to an infinite loop issue while receiving packets in

'mcf_fec_receive'. A privileged user/process inside guest could have

used this issue to crash the Qemu process on the host leading to DoS

(bsc#1013285).

- CVE-2016-9845: The Virtio GPU Device emulator support as vulnerable to

an information leakage issue while processing the

'VIRTIO_GPU_CMD_GET_CAPSET_INFO' command. A guest user/process could

have used this flaw to leak contents of the host memory (bsc#1013767).

- CVE-2016-9846: The Virtio GPU Device emulator support was vulnerable to

a memory leakage issue while up[censored] the cursor data in

update_cursor_data_virgl. A guest user/process could have used this flaw

to leak host memory bytes, resulting in DoS for the host (bsc#1013764).

- CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a

memory leakage flaw when destroying the USB redirector in

'usbredir_handle_destroy'. A guest user/process could have used this

issue to leak host memory, resulting in DoS for a host (bsc#1014109).

- CVE-2016-9908: The Virtio GPU Device emulator support was vulnerable to

an information leakage issue while processing the

'VIRTIO_GPU_CMD_GET_CAPSET' command. A guest user/process could have

used this flaw to leak contents of the host memory (bsc#1014514).

- CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory

leakage issue while processing packet data in 'ehci_init_transfer'. A

guest user/process could have used this issue to leak host memory,

resulting in DoS for the host (bsc#1014111).

- CVE-2016-9912: The Virtio GPU Device emulator support was vulnerable to

a memory leakage issue while destroying gpu resource object in

'virtio_gpu_resource_destroy'. A guest user/process could have used this

flaw to leak host memory bytes, resulting in DoS for the host

(bsc#1014112).

- CVE-2016-9913: VirtFS was vulnerable to memory leakage issue via its

'9p-handle' or '9p-proxy' backend drivers. A privileged user inside

guest could have used this flaw to leak host memory, thus affecting

other services on the host and/or potentially crash the Qemu process on

the host (bsc#1014110).

 

These non-security issues were fixed:

 

- Fixed uint64 property parsing and add regression tests (bsc#937125)

- Added a man page for kvm_stat

- Fix crash in vte (bsc#1008519)

- Various upstream commits targeted towards stable releases (bsc#1013341)
