An update that solves 26 vulnerabilities and has 5 fixes is
now available.

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).
– CVE-2015-5278: Infinite loop in ne2000_receive() function (bsc#945989).
– CVE-2015-6855: hw/ide/core.c did not properly restrict 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).
– CVE-2015-8345: eepro100: infinite loop in processing command block list
(bsc#956829).
– CVE-2015-8613: SCSI: stack based buffer overflow in
megasas_ctrl_get_info (bsc#961358).
– CVE-2015-8619: Stack based OOB write in hmp_sendkey routine (bsc#960334).
– CVE-2015-8743: ne2000: OOB memory access in ioport r/w functions
(bsc#960725).
– CVE-2015-8744: vmxnet3: Incorrect l2 header validation lead to a crash
via assert(2) call (bsc#960835).
– CVE-2015-8745: Reading IMR registers lead to a crash via assert(2) call
(bsc#960707).
– CVE-2016-1568: AHCI use-after-free vulnerability in aio 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 lead to NULL
pointer dereference (bsc#967013).
– CVE-2016-2392: NULL pointer dereference in remote NDIS control message
handling (bsc#967012).
