Here are the details from the Slackware 10.0 ChangeLog:
+--------------------------+
patches/packages/rsync-2.6.3-i486-1.tgz: Upgraded to rsync-2.6.3.
 From the rsync NEWS file:
 A bug in the sanitize_path routine (which affects a non-chrooted
 rsync daemon) could allow a user to craft a pathname that would get
 transformed into an absolute path for certain options (but not for
 file-transfer names). If you're running an rsync daemon with chroot
 disabled, *please upgrade*, ESPECIALLY if the user privs you run
 rsync under is anything above 'nobody'.
 Note that rsync, in daemon mode, sets the 'use chroot' to true by
 default, and (in this default mode) is not vulnerable to this issue.
 I would strongly recommend against setting 'use chroot' to false
 even if you've upgraded to this new package.
 (* Security fix *)
