Announcement ID: SUSE-SU-2018:1362-1
Rating: important
References: #1079405 #1092885
Cross-References: CVE-2018-3639
Affected Products:

SUSE Linux Enterprise Server 12-SP2-LTSS
SUSE Enterprise Storage 4
______________________________________________________________________________
An update that solves one vulnerability and has one errata
is now available.
Description:
This update for qemu fixes several issues.
This security issue was fixed:
- CVE-2018-3639: Spectre v4 vulnerability mitigation support for KVM
guests (bsc#1092885).
Systems with microprocessors utilizing speculative execution and
speculative execution of memory reads before the addresses of all prior
memory writes are known may allow unauthorized disclosure of information
to an attacker with local user access via a side-channel analysis.
This patch permits the new x86 cpu feature flag named "ssbd" to be
presented to the guest, given that the host has this feature, and KVM
exposes it to the guest as well.
For this feature to be enabled please use the qemu commandline
-cpu $MODEL,+spec-ctrl,+ssbd so the guest OS can take advantage of the
feature.
spec-ctrl and ssbd support is also required in the host.
This feature was added:
- Add support for block resize support for xen disks through the monitor
This non-security issue was fixed:
- bsc#1079405: Add new look up path "sys/class/tpm" for tpm cancel path
based
on Linux 4.0 change
