    Description:

    xen was updated to fix 36 security issues.

    These security issues were fixed:

    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).

    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).

    unknown vectors related to page table updates (bsc#960861).
