An update that solves 35 vulnerabilities and has 5 fixes is
now available.

Description:

xen was updated to fix 36 security issues.

These security issues were fixed:

attackers to cause a denial of service and possibly execute arbitrary
code via a large log_num value in a savevm image (bnc#864678).
– CVE-2013-4530: Buffer overflow in hw/ssi/pl022.c allowed remote
attackers to cause a denial of service or possibly execute arbitrary
code via crafted tx_fifo_head and rx_fifo_head values in a savevm image
(bnc#864682).
– 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-2013-4534: Buffer overflow in hw/intc/openpic.c allowed remote
attackers to cause a denial of service or possibly execute arbitrary
code via vectors related to IRQDest elements (bsc#864811).
– 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-2014-3640: The sosendto function in slirp/udp.c allowed local users
to cause a denial of service (NULL pointer dereference) by sending a udp
packet with a value of 0 in the source port and address, which triggers
access of an uninitialized socket (bsc#897654).
– 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).

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-2015-5278: 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-2015-8504: VNC: floating point exception (bsc#958491).

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).
