    Package : util-linux
    Vulnerability : privilege escalation
    Problem type : local
    Debian-specific: no
    CVE ID : CAN-2005-2876
    Debian Bug : 328141 329063

    David Watson discoverd a bug in mount as provided by util-linux and
    other packages such as loop-aes-utils that allows local users to
    bypass filesystem access restrictions by re-mounting it read-only.

    For the old stable distribution (woody) this problem has been fixed in
    version 2.11n-7woody1.

    For the stable distribution (sarge) this problem has been fixed in
    version 2.12p-4sarge1.

    For the unstable distribution (sid) this problem has been fixed in
    version 2.12p-8.

    We recommend that you upgrade your loop-aes-utils 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
