These security issues were fixed:
- CVE-2016-7092: The get_page_from_l3e function in arch/x86/mm.c in Xen
allowed local 32-bit PV guest OS administrators to gain host OS
privileges via vectors related to L3 recursive pagetables (bsc#995785).
- CVE-2016-7093: Xen allowed local HVM guest OS administrators to
overwrite hypervisor memory and consequently gain host OS privileges by
leveraging mishandling of instruction pointer truncation during
emulation (bsc#995789).
- CVE-2016-7094: Buffer overflow in Xen allowed local x86 HVM guest OS
administrators on guests running with shadow paging to cause a denial of
service via a pagetable update (bsc#995792).
- CVE-2016-6836: Information leakage in vmxnet3_complete_packet
(bsc#994761).
- CVE-2016-6888: Integer overflow in packet initialisation in VMXNET3
device driver. Aprivileged user inside guest c... (bsc#994772).
- CVE-2016-6833: Use after free while writing (bsc#994775).
- CVE-2016-6835: Buffer overflow in vmxnet_tx_pkt_parse_headers() in
vmxnet3 deviceemulation. (bsc#994625).
- CVE-2016-6834: An infinite loop during packet fragmentation (bsc#994421).
- CVE-2016-6258: The PV pagetable code in arch/x86/mm.c in Xen allowed
local 32-bit PV guest OS administrators to gain host OS privileges by
leveraging fast-paths for updating pagetable entries (bsc#988675).
- CVE-2016-6259: Xen did not implement Supervisor Mode Access Prevention
(SMAP) whitelisting in 32-bit exception and event delivery, which
allowed local 32-bit PV guest OS kernels to cause a denial of service
(hypervisor and VM crash) by triggering a safety check (bsc#988676).
These non-security issues were fixed:
- bsc#991934: Hypervisor crash in csched_acct
- bsc#992224: During boot of Xen Hypervisor, failed to get contiguous
memory for DMA
- bsc#955104: Virsh reports error 'one or more references were leaked
after disconnect from hypervisor' when 'virsh save' failed due to 'no
response from client after 6 keepalive messages'
- bsc#959552: Migration of HVM guest leads into libvirt segmentation fault
- bsc#993665: Migration of xen guests finishes in: One or more references
were leaked after disconnect from the hypervisor
- bsc#959330: Guest migrations using virsh results in error 'Internal
error: received hangup / error event on socket'
- bsc#990500: VM virsh migration fails with keepalive error:
':virKeepAliveTimerInternal:143 : No response from client'
- bsc#953518: Unplug also SCSI disks in qemu-xen-traditional for upstream
unplug protocol
- bsc#953518: xen_platform: unplug also SCSI disks in qemu-xen
- bsc#971949: xl: Support (by ignoring) xl migrate --live. xl migrations
are always live
- bsc#970135: New virtualization project clock test randomly fails on Xen
- bsc#990970: Add PMU support for Intel E7-8867 v4 (fam=6, model=79)");
