wu-ftpd security update

An updated wu-ftpd package that fixes two security issues is now available.

The wu-ftpd package contains the Washington University FTP (File Transfer
Protocol) server daemon. FTP is a method of transferring files between
machines.

Glenn Stewart discovered a flaw in wu-ftpd. When configured with
"restricted-gid home", an authorized user could use this flaw to
circumvent the configured home directory restriction by using chmod. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CAN-2004-0148 to this issue.

Michael Hendrickx found a flaw in the S/Key login handling. On servers
using S/Key authentication, a remote attacker could overflow a buffer and
potentially execute arbitrary code.

Users of wu-ftpd are advised to upgrade to this updated package, which
contains backported security patches and is not vulnerable to these issues.

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
