CentOS Errata and Security Advisory CESA-2005:504

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.
