Updated telnet packages that fix two bugs are now available for Red Hat Enterprise Linux 6.
Telnet is a popular protocol for logging in to remote systems over the Internet. The telnet-server packages include a telnet service that supports remote logins into the host machine. The telnet service is disabled by default.
- Prior to this update, the telnet utility could enter an infinite loop when the user specified the "-b" parameter with a non-existing network interface. This update modifies the telnet command to print errors when users specify a non-existing network interface.
- Prior to this update, the in.telnetd service could fail to update information in the /var/run/utmp directory when a deadlock occurred in a telnet session. This update modifies telnetd to update /var/run/utmp correctly.
Users of telnet are advised to upgrade to these updated packages, which fix these bugs.
