This update for xen fixes several issues.

These security issues were fixed:

  • CVE-2017-5973: A infinite loop while doing control transfer in
    xhci_kick_epctx allowed privileged user inside the guest to crash the
    host process resulting in DoS (bsc#1025188)
  • CVE-2016-10155: The virtual hardware watchdog ‘wdt_i6300esb’ was
    vulnerable to a memory leakage issue allowing a privileged user to cause
    a DoS and/or potentially crash the Qemu process on the host (bsc#1024183)
  • CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the bitblit copy routine
    cirrus_bitblt_cputovideo failed to check the memory region, allowing for
    an out-of-bounds write that allows for privilege escalation (bsc#1024834)
  • CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation
    support was vulnerable to a memory leakage issue allowing a privileged
    user to leak host memory resulting in DoS (bsc#1024186)
  • CVE-2017-5898: The CCID Card device emulator support was vulnerable to
    an integer overflow flaw allowing a privileged user to crash the Qemu
    process on the host resulting in DoS (bsc#1024307)
  • CVE-2017-2615: An error in the bitblt copy operation could have allowed
    a malicious guest administrator to cause an out of bounds memory access,
    possibly leading to information disclosure or privilege escalation
    (bsc#1023004)
  • CVE-2014-8106: A heap-based buffer overflow in the Cirrus VGA emulator
    allowed local guest users to execute arbitrary code via vectors related
    to blit regions (bsc#907805)
  • CVE-2017-5579: The 16550A UART serial device emulation support was
    vulnerable to a memory leakage issue allowing a privileged user to cause
    a DoS and/or potentially crash the Qemu process on the host (bsc#1022627)
  • CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a
    memory leakage flaw when destroying the USB redirector in
    ‘usbredir_handle_destroy’. A guest user/process could have used this
    issue to leak host memory, resulting in DoS for a host (bsc#1014490)
  • CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory
    leakage issue while processing packet data in ‘ehci_init_transfer’. A
    guest user/process could have used this issue to leak host memory,
    resulting in DoS for the host (bsc#1014507)
  • CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support was vulnerable
    to a divide by zero issue while copying VGA data. A privileged user
    inside guest could have used this flaw to crash the process instance on
    the host, resulting in DoS (bsc#1015169)
  • CVE-2016-9922: The Cirrus CLGD 54xx VGA Emulator support was vulnerable
    to a divide by zero issue while copying VGA data. A privileged user
    inside guest could have used this flaw to crash the process instance on
    the host, resulting in DoS (bsc#1015169)
  • CVE-2016-9101: A memory leak in hw/net/eepro100.c allowed local guest OS
    administrators to cause a denial of service (memory consumption and QEMU
    process crash) by repeatedly unplugging an i8255x (PRO100) NIC device
    (bsc#1013668)
  • CVE-2016-9776: The ColdFire Fast Ethernet Controller emulator support
    was vulnerable to an infinite loop issue while receiving packets in
    ‘mcf_fec_receive’. A privileged user/process inside guest could have
    used this issue to crash the Qemu process on the host leading to DoS
    (bsc#1013657)
  • A malicious guest could have, by frequently rebooting over extended
    periods of time, run the host system out of memory, resulting in a
    Denial of Service (DoS) (bsc#1022871)

These non-security issues were fixed:

  • bsc#1000195: Prevent panic on CPU0 while booting on SLES 11 SP3
  • bsc#1002496: Added support for reloading clvm in block-dmmd block-dmmd
  • bsc#987002: Prevent crash of domU’ after they were migrated from SP3 HV
    to SP4
