Category:Red Hat Local Security Checks
Title:RedHat Update for libvirt RHSA-2018:0030-01
Summary:The remote host is missing an update for the 'libvirt'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'libvirt'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The libvirt library contains a C API for
managing and interacting with the virtualization capabilities of Linux and other
operating systems. In addition, libvirt provides tools for remote management of
virtualized systems. 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 libvirt side of the
CVE-2017-5715 mitigation. Red Hat would like to thank Google Project Zero for
reporting this issue.

Affected Software/OS:
libvirt on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.
