   xen was updated to fix 27 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-2013-4534: 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).
   - 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-2015-5278: Infinite loop in ne2000_receive() function (bsc#945989).
   - 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-2015-8504: VNC: floating point exception (bsc#958491).

     (XSA-165) (bsc#958009).
   - CVE-2015-8558: Infinite loop in ehci_advance_state resulted in DoS
     (bsc#959005).
   - CVE-2015-8743: ne2000: OOB memory access in ioport r/w functions

     (bsc#960707).
   - 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-2016-1571: VMX: intercept issue with INVLPG on non-canonical address
     (XSA-168) (bsc#960862).
