RHBA-2011:1429 - Bug Fix Advisory

Topic

Updated rsh packages that fix one bug are now available for Red Hat Enterprise
Linux 5.

Description

The rsh packages contain programs which allow users to run commands on remote
machines, log in to other machines, copy files between machines (rsh, rlogin and
rcp), and provide an alternate method of executing remote commands (rexec). All
of these programs are run by the xinetd daemon and can be configured using the
Pluggable Authentication Modules (PAM) system and configuration files in the
/etc/xinetd.d/ directory.

This update fixes the following bug:

• The rshd daemon performed redundant calls of the setpwent and endpwent

functions. As a consequence, rshd queried NIS servers with every rsh access.
With this update, these redundant calls were removed so that rshd no longer
contacts NIS servers unnecessarily. (BZ#749322)

All users of rsh are advised to upgrade to these updated packages, which fix
this bug.
