"Updated netcf packages that fix one security issue, several bugs, and
add various enhancements are now available for Red Hat Enterprise
Linux 7.

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

The netcf packages contain a library for modifying the network
configuration of a system. Network configuration is expressed in a
platform-independent XML format, which netcf translates into changes
to the system's 'native' network configuration files.

A denial of service flaw was found in netcf. A specially crafted
interface name could cause an application using netcf (such as the
libvirt daemon) to crash. (CVE-2014-8119)

This issue was discovered by Hao Liu of Red Hat.

The netcf packages have been upgraded to upstream version 0.2.8, which
provides a number of bug fixes and enhancements over the previous
version. (BZ#1206680)

Users of netcf are advised to upgrade to these updated packages, which
fix these bugs and add these enhancements."
