These security issues were fixed:
- CVE-2016-6258: Potential privilege escalation in PV guests (XSA-182)
 (bsc#988675).
- CVE-2016-6259: Missing SMAP whitelisting in 32-bit exception / event
 delivery (XSA-183) (bsc#988676).
- CVE-2016-5337: The megasas_ctrl_get_info function allowed local guest OS
 administrators to obtain sensitive host memory information via vectors
 related to reading device control information (bsc#983973).
- CVE-2016-5338: The (1) esp_reg_read and (2) esp_reg_write functions
 allowed local guest OS administrators to cause a denial of service (QEMU
 process crash) or execute arbitrary code on the host via vectors related
 to the information transfer buffer (bsc#983984).
- CVE-2016-5238: The get_cmd function in hw/scsi/esp.c might have allowed
 local guest OS administrators to cause a denial of service
 (out-of-bounds write and QEMU process crash) via vectors related to
 reading from the information transfer buffer in non-DMA mode
 (bsc#982960).
- CVE-2016-4453: The vmsvga_fifo_run function allowed local guest OS
 administrators to cause a denial of service (infinite loop and QEMU
 process crash) via a VGA command (bsc#982225).
- CVE-2016-4454: The vmsvga_fifo_read_raw function allowed local guest OS
 administrators to obtain sensitive host memory information or cause a
 denial of service (QEMU process crash) by changing FIFO registers and
 issuing a VGA command, which triggered an out-of-bounds read
 (bsc#982224).
- CVE-2016-5126: Heap-based buffer overflow in the iscsi_aio_ioctl
 function allowed local guest OS users to cause a denial of service (QEMU
 process crash) or possibly execute arbitrary code via a crafted iSCSI
 asynchronous I/O ioctl call (bsc#982286).
- CVE-2016-5105: Stack information leakage while reading configuration
 (bsc#982024).
- CVE-2016-5106: Out-of-bounds write while setting controller properties
 (bsc#982025).
- CVE-2016-5107: Out-of-bounds read in megasas_lookup_frame() function
 (bsc#982026).
- CVE-2016-4963: The libxl device-handling allowed local guest OS users
 with access to the driver domain to cause a denial of service
 (management tool confusion) by manipulating information in the backend
 directories in xenstore (bsc#979670).
- CVE-2016-4962: The libxl device-handling allowed local OS guest
 administrators to cause a denial of service (resource consumption or
 management facility confusion) or gain host OS privileges by
 manipulating information in guest controlled areas of xenstore
 (bsc#979620).
- CVE-2016-4952: Out-of-bounds access issue in pvsci_ring_init_msg/data
 routines (bsc#981276).
- CVE-2014-3672: The qemu implementation in libvirt Xen allowed local
 guest OS users to cause a denial of service (host disk consumption) by
 writing to stdout or stderr (bsc#981264).
- CVE-2016-4441: The get_cmd function in the 53C9X Fast SCSI Controller
 (FSC) ... [Please see the references for more information on the vulnerabilities]");
