Red Hat Security Advisory

Synopsis: Important: vdsm security update
Advisory ID: RHSA-2018:0048-01
Product: Red Hat Virtualization
Advisory URL: https://access.redhat.com/errata/RHSA-2018:0048
Issue date: 2018-01-05
=====================================================================

1. Summary:

An update for vdsm is now available for RHEV 3.X Hypervisor and Agents for
Red Hat Enterprise Linux 7 ELS.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

RHEV-H and VDSM for 7 Hosts ELS – noarch

3. Description:

The VDSM service is required by a Virtualization Manager to manage the
Linux hosts. VDSM manages and monitors the host’s storage, memory and
networks as well as virtual machine creation, other host administration
tasks, statistics gathering, and log collection.

Security Fix(es):

* An industry-wide issue was found in the way many modern microprocessor
designs have implemented speculative execution of instructions (a commonly
used performance optimization). There are three primary variants of the
issue which differ in the way the speculative execution can be exploited.
Variant CVE-2017-5715 triggers the speculative execution by utilizing
branch target injection. It relies on the presence of a precisely-defined
instruction sequence in the privileged code as well as the fact that memory
accesses may cause allocation into the microprocessor’s data cache even for
speculatively executed instructions that never actually commit (retire). As
a result, an unprivileged attacker could use this flaw to cross the syscall
and guest/host boundaries and read privileged memory by conducting targeted
cache side-channel attacks. (CVE-2017-5715)

Note: This is the vdsm side of the CVE-2017-5715 mitigation.

Red Hat would like to thank Google Project Zero for reporting this issue.
