7. Problem description:
An explotable buffer overflow security problem in the wu-ftpd daemon has been fixed.

The previous errata for wu-ftpd did not update /var/run/utmp correctly when a session was disconnected. This problem manifested itself as last displaying connections that had terminated as still active.

A minor and obscure problem with members not in a configured class being permitted to login on the second attempt has been fixed.

Thanks go to Gregory A. Lundberg of the WU-FTPD Development Group for supplying the patches.

8. Solution:
For each RPM for your particular architecture, run:

rpm -Uvh filename

where filename is the name of the RPM.

Then restart inetd by typing:

/etc/rc.d/init.d/inet restart

9. Verification:


 MD5 sum                           Package Name

These packages are also PGP signed by Red Hat Inc. for security. Our key is available at: http://www.Red Hat.com/corp/contac t.html

You can verify each package with the following command:

rpm --checksig filename

If you only wish to verify that each package has not been corrupted or tampered with, examine only the md5sum with the following command:

rpm --checksig --nopgp filename
