Updated wget packages fix directory traversal bug

The wget packages shipped with Red Hat Linux 6.2 through 8.0 contain a
security bug which, under certain circumstances, can cause local files to
be written outside the download directory.

[Updated 10 July 2003]
Added packages for Red Hat Linux on IBM iSeries and pSeries systems

Versions of wget prior to 1.8.2-4 contain a bug that permits a malicious
FTP server to create or overwrite files anywhere on the local file system.

FTP clients must check to see if an FTP server's response to the NLST
command includes any directory information along with the list of filenames
required by the FTP protocol (RFC 959, section 4.1.3).

If the FTP client fails to do so, a malicious FTP server can send filenames
beginning with '/' or containing '/../' which can be used to direct a
vulnerable FTP client to write files (such as .forward, .rhosts, .shost,
etc.) that can then be used for later attacks against the client machine.

All Red Hat Linux users using wget < 1.8.2-4 should upgrade
to the errata packages which are not vulnerable to this issue.

Thanks to Steven M. Christey for his work in discovering this issue
in current FTP clients and for providing a patched FTP server to verify
the new packages.

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.
