Description: This update for xen fixes several issues. These security issues were fixed: - CVE-2016-7094: Buffer overflow in Xen allowed local x86 HVM guest OS administrators on guests running with shadow paging to cause a denial of service via a pagetable update (bsc#995792) - CVE-2016-7092: The get_page_from_l3e function in arch/x86/mm.c in Xen allowed local 32-bit PV guest OS administrators to gain host OS privileges via vectors related to L3 recursive pagetables (bsc#995785) - CVE-2016-5403: Unbounded memory allocation allowed a guest administrator to cause a denial of service of the host (bsc#990923) - CVE-2016-6351: The esp_do_dma function in hw/scsi/esp.c, when built with ESP/NCR53C9x controller emulation support, allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or execute arbitrary code on the host via vectors involving DMA read into ESP command buffer (bsc#990843) - CVE-2016-6258: The PV pagetable code in arch/x86/mm.c in Xen allowed local 32-bit PV guest OS administrators to gain host OS privileges by leveraging fast-paths for updating pagetable entries (bsc#988675) - 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-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 length, which allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) via unspecified vectors, involving an SCSI command (bsc#980724) - CVE-2016-4439: The esp_reg_write function in the 53C9X Fast SCSI Controller (FSC) support did not properly check command buffer length, which allowed local guest OS administrators to cause a denial of service (out-of-bounds write and QEMU process crash) or potentially execute arbitrary code on the host via unspecified vectors (bsc#980716) - 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-2016-4480: 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-2016-3960: 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-2016-3158: 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-2016-4001: 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) - CVE-2016-4002: Buffer overflow in the mipsnet_receive function, when the guest NIC is configured to accept large packets, allowed remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes (bsc#975138) These non-security issues were fixed: - bsc#985503: vif-route broken - bsc#978413: PV guest upgrade from sles11sp4 to sles12sp2 alpha3 failed on sles11sp4 xen host. - bsc#954872: Script block-dmmd not working as expected - libxl: error: libxl_dm.c (another modification) - bsc#961600: Poor performance when Xen HVM domU configured with max memory > current memory - bsc#963161: Windows VM getting stuck during load while a VF is assigned to it after upgrading to latest maintenance updates - bsc#976470: Xend fails to start - bsc#973631: AWS EC2 kdump issue Patch Instructions: To install this SUSE Security Update use YaST online_update.
