Title: | Security update for xen (Important) |
Description: |
This update for xen fixes the following issues:
Four new speculative execution information leak issues have been identified in Intel CPUs. (bsc#1111331)
- CVE-2018-12126: Microarchitectural Store Buffer Data Sampling (MSBDS) - CVE-2018-12127: Microarchitectural Fill Buffer Data Sampling (MFBDS) - CVE-2018-12130: Microarchitectural Load Port Data Samling (MLPDS) - CVE-2019-11091: Microarchitectural Data Sampling Uncacheable Memory (MDSUM)
These updates contain the XEN Hypervisor adjustments, that additionaly also use CPU Microcode updates.
The mitigation can be controlled via the 'mds' commandline option, see the documentation.
For more information on this set of vulnerabilities, check out https://www.suse.com/support/kb/doc/?id=7023736
Security issue fixed:
- CVE-2018-20815: Fixed a heap buffer overflow while loading device tree blob (bsc#1130680)
Other fixes:
- Added code to change LIBXL_HOTPLUG_TIMEOUT at runtime.
The included README has details about the impact of this change (bsc#1120095)
- Fixes in Live migrating PV domUs
An earlier change broke live migration of PV domUs without a device model. The migration would stall for 10 seconds while the domU was paused, which caused network connections to drop. Fix this by tracking the need for a device model within libxl. (bsc#1079730, bsc#1098403, bsc#1111025)
