    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.
