    Package : lxr
    Vulnerability : missing filename sanitizing
    Problem-Type : remote
    Debian-specific: no

    Upstream developers of lxr, a general hypertext cross-referencing
    tool, have been alerted of a vulnerability that allows a remote
    attacker to read arbitrary files on the host system as user www-data.
    This could disclose local files that were not meant to be shared with
    the public.

    For the stable distribution (woody) this problem has been
    fixed in version 0.3-3.

    The old stable distribution (potato) is not affected since it does not
    contain an lxr package.

    For the unstable distribution (sid) this problem has been
    fixed in version 0.3-4.

    We recommend that you upgrade your lxr 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.
