RHEL 2.1 / 3 / 4 : telnet (RHSA-2005:504)

Medium Nessus Plugin ID 18501


The remote Red Hat host is missing one or more security updates.


Updated telnet packages that fix an information disclosure issue are now available.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The telnet package provides a command line telnet client.

Gael Delalleau discovered an information disclosure issue in the way the telnet client handles messages from a server. An attacker could construct a malicious telnet server that collects information from the environment of any victim who connects to it. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CVE-2005-0488 to this issue.

Users of telnet should upgrade to this updated package, which contains a backported patch to correct this issue.


Update the affected telnet and / or telnet-server packages.
