Package        : rsync
Vulnerability  : unsanitised input processing
Problem-Type   : remote
Debian-specific: no
Debian Bug     : 265662

The rsync developers have discoverd a security related problem in
rsync, a fast remote file copy program, which offers an attacker to
access files outside of the defined directory.  To exploit this
path-sanitizing bug, rsync has to run in daemon mode with the chroot
option being disabled.  It does not affect the normal send/receive
filenames that specify what files should be transferred.  It does
affect certain option paths that cause auxilliary files to be read or
written.

For the stable distribution (woody) this problem has been fixed in
version 2.5.5-0.6.

For the unstable distribution (sid) this problem has been fixed in
version 2.6.2-3.

We recommend that you upgrade your rsync package.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
