---------------------------------------------------------------------
1. Topic:
Updated ncurses4 compatability packages which fix a potential security
problem are available.
2. Relevant releases/architectures:
Red Hat Linux 7.0 - alpha, i386
Red Hat Linux 7.1 - alpha, i386
Red Hat Linux 7.2 - i386
3. Problem description:
The ncurses library provides a terminal-independent method of screen
handling.
A problem has been found in ncurses version 5.0 that could cause a
buffer overflow. This overflow could be locally exploited if the
library is linked into a program that runs setuid or setgid.
Red Hat Linux ships with a compatibility package 'ncurses4' that is
actually based on ncurses version 5.0 but has been made ABI compatible
with ncurses 4.
No programs that ship with Red Hat Linux are exploitable. A program
could only be exploited if it uses the ncurses 4 compatiblity package
and if it is run setuid or setgid.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2002-0062 to this issue. Thanks to Daniel
Jacobowitz at MontaVista Software for alerting us to this issue.
4. Solution:
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.

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 --nogpg <filename>
