remote exploit possible in lpd

The lpd printing daemon provided by the lpr package posses a remotely
exploitable hole.

The lpd printing daemon possess a flaw in the displayq code which makes a
remote buffer overflow attack possible.

[UPDATE November 7th, 2001]
The initial package released as a fix for this problem itself had a
segfault issue, and would crash when listing remote printers. The broken
package, lpr-0.50.1-1, has been replaced with a working fix.

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.
