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
- bnc#901488: Intel ixgbe driver assigns rx/tx queues per core resulting in irq problems on servers with a large amount of CPU cores
- bsc#945167: Running command: xl pci-assignable-add 03:10.1 secondly show errors
- bsc#949138: Setting vcpu affinity under Xen causes libvirtd abort");
