1.196.1. RHBA-2009:0423: bug fix update
The rsh-server package contains programs which allow users to run commands on remote machines, log in to other machines, copy files between machines (rsh, rlogin and rcp), and provides an alternate method of executing remote commands (rexec). All of these programs are run by xinetd and can be configured through the Pluggable Authentication Modules (PAM) system, and through configuration files in the /etc/xinetd.d/ directory.
All users of rsh are advised to upgrade to these updated packages, which resolve these issues.
