Impact: Systems that have been manually configured to use rlogin and host.equiv may unexpectedly permit root login

Description: The manpage for the configuration file hosts.equiv indicates that entries do not apply to root. However, an implementation issue in rlogind causes these entries to also apply to root. This update addresses the issue by properly disallowing rlogin from the root user if the remote system is in hosts.equiv. The rlogin service is not enabled by default in Mac OS X, and must be manually configured in order to be enabled. Credit to Ralf Meyer for reporting this issue.
