Synopsis :

The remote openSUSE host is missing a security update.

Description :

xen was updated to fix 26 security issues.

These security issues were fixed :

- CVE-2013-4533: Buffer overflow in the pxa2xx_ssp_load
function in hw/arm/pxa2xx.c allowed remote attackers to
cause a denial of service or possibly execute arbitrary
code via a crafted s->rx_level value in a savevm image
(bsc#864655).

- CVE-2013-4537: The ssi_sd_transfer function in
hw/sd/ssi-sd.c allowed remote attackers to execute
arbitrary code via a crafted arglen value in a savevm
image (bsc#864391).

- CVE-2013-4538: Multiple buffer overflows in the
ssd0323_load function in hw/display/ssd0323.c allowed
remote attackers to cause a denial of service (memory
corruption) or possibly execute arbitrary code via
crafted (1) cmd_len, (2) row, or (3) col values; (4)
row_start and row_end values; or (5) col_star and
col_end values in a savevm image (bsc#864769).

- CVE-2013-4539: Multiple buffer overflows in the
tsc210x_load function in hw/input/tsc210x.c might have
allowed remote attackers to execute arbitrary code via a
crafted (1) precision, (2) nextprecision, (3) function,
or (4) nextfunction value in a savevm image
(bsc#864805).

- CVE-2014-0222: Integer overflow in the qcow_open
function in block/qcow.c allowed remote attackers to
cause a denial of service (crash) via a large L2 table
in a QCOW version 1 image (bsc#877642).

- CVE-2014-3689: The vmware-vga driver
(hw/display/vmware_vga.c) allowed local guest users to
write to qemu memory locations and gain privileges via
unspecified parameters related to rectangle handling
(bsc#901508).

- CVE-2014-7815: The set_pixel_format function in ui/vnc.c
allowed remote attackers to cause a denial of service
(crash) via a small bytes_per_pixel value (bsc#902737).

- CVE-2014-9718: The (1) BMDMA and (2) AHCI HBA interfaces
in the IDE functionality had multiple interpretations of
a function's return value, which allowed guest OS users
to cause a host OS denial of service (memory consumption
or infinite loop, and system crash) via a PRDT with zero
complete sectors, related to the bmdma_prepare_buf and
ahci_dma_prepare_buf functions (bsc#928393).

- CVE-2015-1779: The VNC websocket frame decoder allowed
remote attackers to cause a denial of service (memory
and CPU consumption) via a large (1) websocket payload
or (2) HTTP headers section (bsc#924018).

function (bsc#945989).

the commands accepted by an ATAPI device, which allowed
guest users to cause a denial of service or possibly
have unspecified other impact via certain IDE commands,
as demonstrated by a WIN_READ_NATIVE_MAX command to an
empty drive, which triggers a divide-by-zero error and
instance crash (bsc#945404).

- CVE-2015-7512: Buffer overflow in the pcnet_receive
function in hw/net/pcnet.c, when a guest NIC has a
larger MTU, allowed remote attackers to cause a denial
of service (guest OS crash) or execute arbitrary code
via a large packet (bsc#957162).

port commands (bsc#961332).

- CVE-2016-1570: The PV superpage functionality in
arch/x86/mm.c allowed local PV guests to obtain
sensitive information, cause a denial of service, gain
privileges, or have unspecified other impact via a
crafted page identifier (MFN) to the (1)
MMUEXT_MARK_SUPER or (2) MMUEXT_UNMARK_SUPER sub-op in
the HYPERVISOR_mmuext_op hypercall or (3) unknown
vectors related to page table updates (bsc#960861).

- CVE-2016-1714: nvram: OOB r/w access in processing
firmware configurations (bsc#961691).

- CVE-2016-1981: e1000 infinite loop in start_xmit and
e1000_receive_iov routines (bsc#963782).

- CVE-2016-2198: EHCI NULL pointer dereference in
ehci_caps_write (bsc#964413).

- CVE-2016-2391: usb: multiple eof_timers in ohci module
