  - CVE-2016-7156: In the VMWARE PVSCSI paravirtual SCSI bus     a infinite loop issue could have allowed a privileged     user inside guest to crash the Qemu process resulting in     DoS (bsc#997859)

The update package also includes non-security fixes. See advisory for details.

kvm was updated to fix 16 security issues. These security issues were fixed :

  - CVE-2015-6815: e1000 NIC emulation support was     vulnerable to an infinite loop issue. A privileged user     inside guest could have used this flaw to crash the Qemu     instance resulting in DoS. (bsc#944697).

  - CVE-2016-2391: The ohci_bus_start function in the USB     OHCI emulation support (hw/usb/hcd-ohci.c) in QEMU     allowed local guest OS administrators to cause a denial     of service (NULL pointer dereference and QEMU process     crash) via vectors related to multiple eof_timers     (bsc#967013).

  - CVE-2016-2392: The is_rndis function in the USB Net     device emulator (hw/usb/dev-network.c) in QEMU did not     properly validate USB configuration descriptor objects,     which allowed local guest OS administrators to cause a     denial of service (NULL pointer dereference and QEMU     process crash) via vectors involving a remote NDIS     control message packet (bsc#967012).

  - CVE-2016-4453: The vmsvga_fifo_run function in     hw/display/vmware_vga.c in QEMU allowed local guest OS     administrators to cause a denial of service (infinite     loop and QEMU process crash) via a VGA command     (bsc#982223).

  - CVE-2016-4454: The vmsvga_fifo_read_raw function in     hw/display/vmware_vga.c in QEMU 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 triggers an out-of-bounds read     (bsc#982222).

  - CVE-2016-5105: The megasas_dcmd_cfg_read function in     hw/scsi/megasas.c in QEMU, when built with MegaRAID SAS     8708EM2 Host Bus Adapter emulation support, used an     uninitialized variable, which allowed local guest     administrators to read host memory via vectors involving     a MegaRAID Firmware Interface (MFI) command     (bsc#982017).

  - CVE-2016-5106: The megasas_dcmd_set_properties function     in hw/scsi/megasas.c in QEMU, when built with MegaRAID     SAS 8708EM2 Host Bus Adapter emulation support, allowed     local guest administrators to cause a denial of service     (out-of-bounds write access) via vectors involving a     MegaRAID Firmware Interface (MFI) command (bsc#982018).

  - CVE-2016-5107: The megasas_lookup_frame function in     QEMU, when built with MegaRAID SAS 8708EM2 Host Bus     Adapter emulation support, allowed local guest OS     administrators to cause a denial of service     (out-of-bounds read and crash) via unspecified vectors     (bsc#982019).

  - CVE-2016-5126: Heap-based buffer overflow in the     iscsi_aio_ioctl function in block/iscsi.c in QEMU     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#982285).

  - CVE-2016-5238: The get_cmd function in hw/scsi/esp.c in     QEMU 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#982959).

  - CVE-2016-5337: The megasas_ctrl_get_info function in     hw/scsi/megasas.c in QEMU allowed local guest OS     administrators to obtain sensitive host memory     information via vectors related to reading device     control information (bsc#983961).

  - CVE-2016-5338: The (1) esp_reg_read and (2)     esp_reg_write functions in hw/scsi/esp.c in QEMU allowed     local guest OS administrators to cause a denial of     service (QEMU process crash) or execute arbitrary code     on the QEMU host via vectors related to the information     transfer buffer (bsc#983982).

  - CVE-2016-5403: The virtqueue_pop function in     hw/virtio/virtio.c in QEMU allowed local guest OS     administrators to cause a denial of service (memory     consumption and QEMU process crash) by submitting     requests without waiting for completion (bsc#991080).

  - CVE-2016-6490: Infinite loop in the virtio framework. A     privileged user inside the guest could have used this     flaw to crash the Qemu instance on the host resulting in     DoS (bsc#991466).

  - CVE-2016-7116: Host directory sharing via Plan 9 File     System(9pfs) was vulnerable to a directory/path     traversal issue. A privileged user inside guest could     have used this flaw to access undue files on the host     (bsc#996441).

  - CVE-2014-7815: The set_pixel_format function in ui/vnc.c     in QEMU allowed remote attackers to cause a denial of     service (crash) via a small bytes_per_pixel value     (bsc#902737).
