RHBA-2007:1012 - Bug Fix Advisory

Topic

Updated telnet-server packages that fixe a bug are now available.

Description

Telnet is a popular protocol for logging in to remote systems over the
Internet. The telnet-server package includes a telnet daemon that
supports remote logins into the host machine. The telnet daemon is
disabled by default.

The telnet daemon refused connections when the reverse records for the
host you were connecting to did not exist, for example, when configured
nameservers were unavailable, and the host you were connecting to was not
in "/etc/hosts". Telnet sessions would terminate with a "Temporary failure
in name resolution: Illegal seek" error.

Users of the telnet-server packages are advised to upgrade to these
updated packages, which resolve this issue.
