3. Description:

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.

4. Solution:

Before applying this update, make sure all previously released errata
