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:

CAN-2005-1855

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

CAN-2005-1856

    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.
