Package        : backupninja
Vulnerability  : insecure temporary file
Problem type   : local
Debian-specific: no
CVE ID         : 

Moritz Muehlenhoff discovered the handler code for backupninja creates
a temporary file with a predictable filename, leaving it vulnerable to
a symlink attack. 

The old stable distribution (woody) does not contain the backupninja package.

For the stable distribution (sarge) this problem has been fixed in
version 0.5-3sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 0.8-2.

We recommend that you upgrade your backupninja 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.
