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.

where [filenames] is a list of the RPMs you wish to upgrade. Only those=20
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=20
you=20
can also use wildcards (*.rpm) if your current directory *only* contains=20
