    Debian Security Advisory DSA 735-2 security@debian.org

    Package : sudo
    Vulnerability : pathname validation race
    Problem type : local
    Debian-specific: no
    CVE Id(s) : CAN-2005-1993
    Debian Bug : 315115

    A local user who has been granted permission to run commands via sudo
    could run arbitrary commands as a privileged user due to a flaw in
    sudo's pathname validation. This bug only affects configurations which
    have restricted user configurations prior to an ALL directive in the
    configuration file. A workaround is to move any ALL directives to the
    beginning of the sudoers file; see the advisory at
    http://www.sudo.ws/sudo/alerts/path_race.html for more information.

    For the old stable Debian distribution (woody), this problem has been
    fixed in version 1.6.6-1.3woody1.

    For the current stable distribution (sarge), this problem has been fixed
    in version 1.6.8p7-1.1sarge1.

    For the unstable distribution, this problem has been fixed in version
    1.6.8p9-1.

    The only change since DSA 735-1 is the addition of certain architectures
    which were not available in the original advisory.

    We recommend that you upgrade your sudo 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.
