RHBA-2014:0868 - telnet bug fix update

Synopsis

telnet bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated telnet packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

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.

This update fixes the following bugs:

  • 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. (BZ#772912)

  • 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. (BZ#832059)

Users of telnet are advised to upgrade to these updated packages, which fix these bugs.

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258
