An update that solves 8 vulnerabilities and has 8 fixes is
now available.
Description:
xen was updated to version 4.4.3 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
– 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
