[slackware-security]  rsync security update (SSA:2003-337-01)

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:

  http://rsync.samba.org
