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.

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
