These security issues were fixed:
- CVE-2017-5753, CVE-2017-5715, CVE-2017-5754: Prevent information leaks
via side effects of speculative execution, aka 'Spectre' and 'Meltdown'
attacks (bsc#1074562, bsc#1068032)
- CVE-2017-15595: x86 PV guest OS users were able to cause a DoS
(unbounded recursion, stack consumption, and hypervisor crash) or
possibly gain privileges via crafted page-table stacking (bsc#1061081)
- CVE-2017-17566: Prevent PV guest OS users to cause a denial of service
(host OS crash) or gain host OS privileges in shadow mode by mapping a
certain auxiliary page (bsc#1070158).
- CVE-2017-17563: Prevent guest OS users to cause a denial of service
(host OS crash) or gain host OS privileges by leveraging an incorrect
mask for reference-count overflow checking in shadow mode (bsc#1070159).
- CVE-2017-17564: Prevent guest OS users to cause a denial of service
(host OS crash) or gain host OS privileges by leveraging incorrect error
handling for reference counting in shadow mode (bsc#1070160).
- CVE-2017-17565: Prevent PV guest OS users to cause a denial of service
(host OS crash) if shadow mode and log-dirty mode are in place, because
of an incorrect assertion related to M2P (bsc#1070163).
- CVE-2018-5683: The vga_draw_text function allowed local OS guest
privileged users to cause a denial of service (out-of-bounds read and
QEMU process crash) by leveraging improper memory address validation
(bsc#1076116).
- CVE-2017-18030: The cirrus_invalidate_region function allowed local OS
guest privileged users to cause a denial of service (out-of-bounds array
access and QEMU process crash) via vectors related to negative pitch
(bsc#1076180).
These non-security issues were fixed:
- bsc#1067317: pass cache=writeback<pipe>unsafe<pipe>directsync to qemu depending on
the libxl disk settings
- bsc#1051729: Prevent invalid symlinks after install of SLES 12 SP2
- bsc#1035442: Increased the value of LIBXL_DESTROY_TIMEOUT from 10 to 100
seconds. If many domUs shutdown in parallel the backends couldn't keep up
- bsc#1027519: Added several upstream patches");
