  script_tag(name:"insight", value:"Rsync is a file transfer client and server.

A security problem which may lead to unauthorized machine access
or code execution has been fixed by upgrading to rsync-2.5.7.
This problem only affects machines running rsync in daemon mode,
and is easier to exploit if the non-default option 'use chroot = no'
is used in the /etc/rsyncd.conf config file.

Any sites running an rsync server should upgrade immediately.

For complete information, see the rsync home page:
