Subject: [FLSA-2005:152583] Updated telnet packages fix security issues

---------------------------------------------------------------------
               Fedora Legacy Update Advisory

Synopsis:          Updated telnet packages fix security issues
Advisory ID:       FLSA:152583
Issue date:        2005-07-11
Product:           Red Hat Linux, Fedora Core
Keywords:          Bugfix
CVE Names:         CAN-2005-0468 CAN-2005-0469
---------------------------------------------------------------------


---------------------------------------------------------------------
1. Topic:

Updated telnet packages that fix two buffer overflow vulnerabilities are
now available.

The telnet package provides a command line telnet client. The telnet-
server package includes a telnet daemon, telnetd, that supports remote
login to the host machine.

2. Relevant releases/architectures:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386
Fedora Core 1 - i386

3. Problem description:

Two buffer overflow flaws were discovered in the way the telnet client
handles messages from a server. An attacker may be able to execute
arbitrary code on a victim's machine if the victim can be tricked into
connecting to a malicious telnet server. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the names CAN-2005-0468
and CAN-2005-0469 to these issues.

Users of telnet should upgrade to this updated package, which contains
backported patches to correct these issues.

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 yum and apt.  Many
people find this an easier way to apply updates.  To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system.  This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the sha1sum with the following command:

    sha1sum <filename>
