EulerOS 2.0 SP2 : qemu-kvm (EulerOS-SA-2018-1200)

Medium Nessus Plugin ID 110864

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the qemu-kvm packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerability :

- An industry-wide issue was found in the way many modern
microprocessor designs have implemented speculative
execution of Load & Store instructions (a commonly used
performance optimization). It relies on the presence of
a precisely-defined instruction sequence in the
privileged code as well as the fact that memory read
from address to which a recent memory write has
occurred may see an older value and subsequently cause
an update 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 read privileged memory by
conducting targeted cache side-channel attacks.
(CVE-2018-3639)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution

Update the affected qemu-kvm package.
