Problem description: 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 CAN-2005-0488 to this issue. Users of telnet should upgrade to this updated package, which contains a backported patch to correct this issue. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via Red Hat Network. 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. 5.
