| Descripción: | Summary:
The remote host is missing an update for the 'kernel, kmod-virtualbox, kmod-xtables-addons' package(s) announced via the MGASA-2019-0332 advisory.
Vulnerability Insight:
This kernel update is based on the upstream 5.3.11 and fixes at least the
following security issues:
Insufficient access control in a subsystem for Intel (R) processor graphics
may allow an authenticated user to potentially enable escalation of
privilege via local access (CVE-2019-0155).
TSX Asynchronous Abort condition on some CPUs utilizing speculative
execution may allow an authenticated user to potentially enable
information disclosure via a side channel with local access
(CVE-2019-11135).
Improper invalidation for page table updates by a virtual guest operating
system for multiple Intel(R) Processors may allow an authenticated user to
potentially enable denial of service of the host system via local access
(CVE-2018-12207).
For proper mitigations and fixes for these issues, a microcode update is
also needed, either with a bios/uefi update from your hardware vendor or
by installing the microcode-0.20191112-1.mga7.nonfree update (mga#25688).
For other upstream fixes in this update, see the referenced changelogs.
