Netwosix Linux Security Advisory #2004-0017 <http://www.netwosix.org>
-
-----------------------------------------------------------------------------------
Package name: rsync
Summary: Exposure of System Information
Date: 2004-08-17
Affected versions: Netwosix 1.0 Netwosix 1.1
************************************************************************************
- -> Package description:
- ------------------------
rsync is an open source utility that provides fast incremental file transfer.
rsync is freely available under the GNU General Public License version 2
- -> Problem description:
- ------------------------
There is a path-sanitizing bug that affects daemon mode in all recent rsync
versions (including 2.6.2) but only if chroot is disabled. It does NOT affect
the normal send/receive filenames that specify what files should be
transferred (this is because these names happen to get sanitized twice, and
thus the second call removes any lingering leading slash(es) that the first
call left behind). It does affect certain option paths that cause auxilliary
files to be read or written.
- -> Action:
- ------------------------
We recommend that all systems with this package installed be upgraded.
Please note that if you do not need the functionality provided by this
package, you may want to remove it from your system.

- -> About Linux Netwosix:
- ---------------------------------
Linux Netwosix is a powerful and optimized Linux distribution for servers
and Network Security related jobs. It can also be used for special operations
such as penetration testing with its big collection of security oriented
software and sources. It's a light distribution created for the requirements
of every SysAdmin and it's very portable and highly configurable. Our
philosophy is to give greater liberty for configuration to the SysAdmin.
Only in this way can he/she configure a powerful and stable server machine.
Linux Netwosix also has a powerful ports system (Nepote) similar to the xBSD
systems but more flexible and usable.
