From Red Hat Security Advisory 2018:1929 :
An update for libvirt is now available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having a security impact of Low. 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.
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) :
libvirt: Resource exhaustion via qemuMonitorIORead() method (CVE-2018-5748)
libvirt: Incomplete fix for CVE-2018-5748 triggered by QEMU guest agent (CVE-2018-1064)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
The CVE-2018-5748 issue was discovered by Daniel P. Berrange (Red Hat) and Peter Krempa (Red Hat), and the CVE-2018-1064 issue was discovered by Daniel P. Berrange (Red Hat).
