Description:   Two vulnerabilities were reported in Rsync. A remote user can bypass access controls to access files on the target system.

Users that have configured rsync as a writable rsync daemon are affected.

If the daemon is configured with the 'use chroot = no' setting, a remote user can cause rsync to create a symbolic link to a file located outside of the module's hierarchy.

If the daemon is configured with an "exclude", "exclude from", or "filter" option, a remote user can access restricted files. The remote user may be able to write to the file (in accordance with the file's permission).

Impact:   A remote user can bypass access controls to access files on the target system.
Solution:   Apple has issued a fix (Security Update 2008-005), which can be downloaded and installed via Software Update preferences, or from Apple Downloads at:
