"Updated kdenetwork packages that fix a file descriptor leak are now
available.

This update has been rated as having low security impact by the Red
Hat Security Response Team

The kdenetwork packages contain a collection of networking
applications for the K Desktop Environment.

A bug was found in the way kppp handles privileged file descriptors. A
malicious local user could make use of this flaw to modify the
/etc/hosts or /etc/resolv.conf files, which could be used to spoof
domain information. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2005-0205 to this issue.

Please note that the default installation of kppp on Red Hat
Enterprise Linux uses consolehelper and is not vulnerable to this
issue. However, the kppp FAQ provides instructions for removing
consolehelper and running kppp suid root, which is a vulnerable
configuration.

Users of kdenetwork should upgrade to these updated packages, which
contain a backported patch, and are not vulnerable to this issue."
