    Package        : mantis
    Vulnerability  : cross site code execution, privilege escalation
    Problem-Type   : remote
    Debian-specific: no
    Jeroen Latour pointed out that we missed one uninitialized variable in
    DSA 153-1, which was insecurely used with file inclusions in the
    Mantis package, a php based bug tracking system.  When such occasions
    are exploited, a remote user is able to execute arbitrary code under
    the webserver user id on the web server hosting the mantis system.
    Jeroen Latour discovered that Mantis did not check all user input,
    especially if they do not come directly from form fields. This opens
    up a wide variety of SQL poisoning vulnerabilities on systems without
    magic_quotes_gpc enabled.  Most of these vulnerabilities are only
    exploitable in a limited manner, since it is no longer possible to
    execute multiple queries using one call to mysql_query().  There is
    one query which can be tricked into changing an account's access
    Jeroen Latour also reported that it is possible to instruct Mantis to
    show reporters only the bugs that they reported, by setting the
    limit_reporters option to ON.  However, when formatting the output
    suitable for printing, the program did not check the limit_reporters
    option and thus allowed reporters to see the summaries of bugs they
    did not report.
    Jeroen Latour discovered that the page responsible for displaying a
    list of bugs in a particular project, did not check whether the user
    actually has access to the project, which is transmitted by a cookie
    variable.  It accidently trusted the fact that only projects
    accessible to the user were listed in the drop-down menu.  This
    provides a malicious user with an opportunity to display the bugs of a
    private project selected.
    These problems have been fixed in version 0.17.1-2.2 for the current
    stable distribution (woody) and in version 0.17.4a-2 for the unstable
    distribution (sid).  The old stable distribution (potato) is not
    affected, since it doesn't contain the mantis package.
    We recommend that you upgrade your mantis packages immediately.
    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.

      These files will probably be moved into the stable distribution on
      its next revision.
