    I've just detected a new Product Alert on iPlanets Web Site. I'm
    sending this information because I was not able to find it in the
    bugtraq archive yet. iPlanet does not seem to inform bugtraq
    (why?). The information posted herein can be found in
    http://www.iplanet.com/products/iplanet_web_enterprise/iwsalert5.11.html.

    Important iPlanet Web Server 4.1 SP 3-7
    Product Alert:
    Recommend Immediate Patch/Upgrade
     
    May 11, 2001
    Two vulnerabilities have been identified within iPlanet Web Server(iWS):
    
    
    1) A manipulation of the HTTP request headers sent to iWS, Enterprise
    Edition version 4.1 Service Packs 3 through 7 (iWS4.1sp3-7) can be
    exploited as a Denial of Service attack against users of iWS4.1sp3-7
    on the Microsoft Windows NT platform*.
    
    2) A manipulation of the HTTP request headers sent to iWS or Netscape
    Enterprise Server (NES) that have the Web Publisher feature enabled
    can be exploited as a Denial of Service attack.
    
    The risk from these attacks is completely eliminated by deployment of
    the following NSAPI.   
    
    aix_flexlog2.tgz
    dec-osf1_flexlog2.tgz
    hpux_flexlog2.tgz
    linux_flexlog2.tgz
    solaris_flexlog2.tgz
    winnt_flexlog2.zip
    
    While only installations of iWS4.1sp3-7 on Windows NT are
    immediately vulnerable to this attack, all users of iWS4.1sp3-7 are
    advised to install the NSAPI.
