without the do_brk() vulnerability, and upgrade to version 2.5.7 of rsync:

    # emerge sync
    # emerge -pv '>=net-misc/rsync-2.5.7'
    # emerge '>=net-misc/rsync-2.5.7'

Review your /etc/rsync/rsyncd.conf configuration file. Ensure that the use
chroot='no' command is commented out or removed, or change use chroot='no'
to use chroot='yes'.  Then, if necessary, restart rsyncd:

    # /etc/init.d/rsyncd restart");
