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.
