fix a security issue. When running an rsync server without the chroot option
it is possible for an attacker to write outside of the allowed directory.
Any sites running rsync in that mode should upgrade right away (and should
probably look into using the chroot option as well).

Here are the details from the Slackware 9.1 ChangeLog:
+--------------------------+
Sun May 2 17:16:41 PDT 2004
patches/packages/rsync-2.6.2-i486-1.tgz: Upgraded to rsync-2.6.2.
 Rsync before 2.6.1 does not properly sanitize paths when running a
 read/write daemon without using chroot, allowing remote attackers to
 write files outside of the module's path.
 For more details, see:
