Package : backup manager
Vulnerability : insecure permissions and tempfile
Problem-Type : local
Debian-specific: no
CVE ID : CAN-2005-1855 CAN-2005-1856
Debian Bug : 308897 315582

Two bugs have been found in backup-manager, a command-line driven
backup utility. The Common Vulnerabilities and Exposures project
identifies the following problems:


Jeroen Vermeulen discovered that backup files are created with
default permissions making them world readable, even though they
may contain sensitive information.


Sven Joachim discovered that the optional CD-burning feature of
backup-manager uses a hardcoded filename in a world-writable
directory for logging. This can be subject to a symlink attack.

The old stable distribution (woody) does not provide the
backup-manager package.

For the stable distribution (sarge) these problems have been fixed in
version 0.5.7-1sarge1.

For the unstable distribution (sid) these problems have been fixed in
version 0.5.8-2.

We recommend that you upgrade your backup-manager 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.
