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.
