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

- bsc#941074: Device 51728 could not be connected. Hotplug scripts not

working
