Description:

 

This update for xen fixes several issues.

 

These security issues were fixed:

guest OS users to cause a denial of service (host disk consumption) by

writing to stdout or stderr (bsc#981264).

- CVE-2016-3158: The xrstor function did not properly handle writes to the

hardware FSW.ES bit when running on AMD64 processors, which allowed

local guest OS users to obtain sensitive register content information

from another guest by leveraging pending exception and mask bits

(bsc#973188).

- CVE-2016-3159: The fpu_fxrstor function in arch/x86/i387.c did not

properly handle writes to the hardware FSW.ES bit when running on AMD64

processors, which allowed local guest OS users to obtain sensitive

register content information from another guest by leveraging pending

exception and mask bits (bsc#973188).

- CVE-2016-3710: The VGA module improperly performed bounds checking on

banked access to video memory, which allowed local guest OS

administrators to execute arbitrary code on the host by changing access

modes after setting the bank register, aka the "Dark Portal" issue

(bsc#978164)

- CVE-2016-3960: Integer overflow in the x86 shadow pagetable code allowed

local guest OS users to cause a denial of service (host crash) or

possibly gain privileges by shadowing a superpage mapping (bsc#974038).

- CVE-2016-4001: Buffer overflow in the stellaris_enet_receive function,

when the Stellaris ethernet controller is configured to accept large

packets, allowed remote attackers to cause a denial of service (QEMU

crash) via a large packet (bsc#975130).

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-2016-4480: The guest_walk_tables function in

arch/x86/mm/guest_walk.c in Xen did not properly handle the Page Size

(PS) page table entry bit at the L4 and L3 page table levels, which

might have allowed local guest OS users to gain privileges via a crafted

mapping of memory (bsc#978295).

- CVE-2016-4952: Out-of-bounds access issue in pvsci_ring_init_msg/data

routines (bsc#981276)

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-2016-4963: The libxl device-handling allowed local guest OS users

with access to the driver domain to cause a denial of service

process crash) or possibly execute arbitrary code via a crafted iSCSI

asynchronous I/O ioctl call (bsc#982286)

- 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-2016-5337: 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
