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) support did not properly check DMA ... [Please see the references for more information on the vulnerabilities]");
