   An update that solves 8 vulnerabilities and has 6 fixes is
   now available.

Description:

   xen was updated to fix nine security issues.

   These security issues were fixed:
   - CVE-2015-4037: The slirp_smb function in net/slirp.c created temporary
     files with predictable names, which allowed local users to cause a
     denial of service (instantiation failure) by creating /tmp/qemu-smb.*-*
     files before the program (bsc#932267).
   - CVE-2014-0222: Integer overflow in the qcow_open function allowed remote
     attackers to cause a denial of service (crash) via a large L2 table in a
     QCOW version 1 image (bsc#877642).
   - CVE-2015-7835: Uncontrolled creation of large page mappings by PV guests
     (bsc#950367).
   - CVE-2015-7311: libxl in Xen did not properly handle the readonly flag on
     disks when using the qemu-xen device model, which allowed local guest
     users to write to a read-only disk image (bsc#947165).
   - CVE-2015-5239: Integer overflow in vnc_client_read() and
     protocol_client_msg() (bsc#944463).
   - CVE-2015-6815: With e1000 NIC emulation support it was possible to enter
     an infinite loop (bsc#944697).
   - CVE-2015-7969: Leak of main per-domain vcpu pointer array leading to
     denial of service (bsc#950703).
   - CVE-2015-7969: Leak of per-domain profiling- related vcpu pointer array
     leading to denial of service (bsc#950705).
   - CVE-2015-7971: Some pmu and profiling hypercalls log without rate
     limiting (bsc#950706).

   These non-security issues were fixed:
   - bsc#907514: Bus fatal error: SLES 12 sudden reboot has been observed
   - bsc#910258: SLES12 Xen host crashes with FATAL NMI after shutdown of
     guest with VT-d NIC
   - bsc#918984: Bus fatal error: SLES11-SP4 sudden reboot has been observed
   - bsc#923967: Partner-L3: Bus fatal error: SLES11-SP3 sudden reboot has
     been observed
