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 updating 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)
