    Tons of Linux updates have been released this week. Most important
    was a gaggle of bugs found in the kernel (reported in this issue
    as {01.43.015}. You might want to think about popping over to
    www.kernel.org (or mirror) and grabbing the latest and greatest.

    What's interesting about this recent batch of security fixes is the
    fact that (one of) the kernel maintainers was tight-lipped about the
    nature of the problem because of the legislation set forth by the
    Digital Millennium Copyright Act. It's unfortunate to see that legal
    acts such as the DMCA, and the upcoming SSSCA, are impacting the IT
    community's ability to be informed about security problems. Hopefully,
    the day won't come were newsletters such as SAC are illegal under
    some such silly computer crime law.

    *** {01.43.002} Win - Citrix MetaFrame session flood/timeout DoS

    A denial of service attack has been found in various versions of
    Citrix' MetaFrame. It's possible for a remote attacker to cause the
    entire system to crash by using a particular connection method and
    then allowing the connection to timeout.

    The vendor has confirmed this vulnerability and released various hot
    fixes, which are available at:
    http://www.citrix.com/support

    *** {01.43.010} Win - SSPD server malformed data DoS

    The SSPD server included with Windows ME has been found susceptible to
    a denial of service attack whereby a remote attacker connects to the
    service and sends a few unexpected characters, causing the service
    to crash.

    This vulnerability has not been confirmed.

    *** {01.43.012} Win - MS01-052: Invalid RDP causes Terminal Server to
                    crash

    Microsoft has released MS01-052 ("Invalid RDP causes Terminal Server
    to crash"). A particular series of data sent to a Terminal Server
    service can cause the system to crash, requiring a reboot. This
    obviously leads to a remote denial of service.

    A report was released this week indicating that Internet Explorer
    versions prior to 6.0 are vulnerable to Cross-Site Scripting for

    execute arbitrary script under lax security restrictions.

    This vulnerability has not been confirmed.

    *** {01.43.015} Linux - Linux kernel security updates (both 2.2 and 2.4)

    A lot of movement has happened in the last week with the Linux kernels.

    First off, 2.2.19 and prior, as well as 2.4.9 and prior, are vulnerable
    to another ptrace() bug, which allows a local user to gain root access.

    There is also a local denial of service bug, which is related to
    nested symlinks in kernels prior to 2.4.12.

    Note that the latest 2.4 kernel is 2.4.13. Kernel 2.2.20 will
    be released shortly -- in the meantime, use the 2.2.19 patches
    available at:
    http://archives.neohapsis.com/archives/bugtraq/2001-10/0135.html

    *** {01.43.017} Cross - nvi file name format string vulnerability

    The nvi file editor has been found to contain a format string
    vulnerability in the handling of file names. It's possible for a
    user to be tricked into opening a malicious file, which could execute
    arbitrary code under the user's privileges.

    Debian has confirmed this vulnerability. Updated Debian DEBs are

    *** {01.43.020} Cross - Network Query Tool CGI command execution

    The Network Query Tool CGI version 1.0, in both standalone and PHPNuke
    add-on versions, does not properly filter out Unix metacharacters from
    user-supplied data before passing them on to a command line shell
    for execution. Thus, it's possible for a remote attack to execute
    arbitrary commands.

    This vulnerability has not been confirmed.

    *** {01.43.021} Cross - Webmin insecure local temp file handling

    create temporary files, potentially allowing local attackers to

    *** {01.43.027} Cross - WebCart CGI 'nextpage' parameter command
                    execution

    Mountain Network Systems' WebCart CGI version 8.4 has been found to
    not properly filter metacharacters from the 'nextpage' URL parameter
    before passing them to a shell. A remote attacker is thereby allowed
    to execute arbitrary command line commands under the Web server's
    privileges.

    This vulnerability has not been confirmed.
