      Title:  Security Advisory with Netscape servers on HP-UX

-------------------------------------------------------------------------
         HEWLETT-PACKARD SECURITY ADVISORY: #00080, 29 July 1998
-------------------------------------------------------------------------

The information in the following Security Advisory should be acted upon
as soon as possible.  Hewlett-Packard Company will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Advisory as soon as possible.

-------------------------------------------------------------------------
PROBLEM:   The Million Question vulnerability affects the use of RSA
           Data Security encryption algorithms with Netscape server
           products that support Secure Sockets Layer (SSL).  The nature
           of the vulnerability is that a single encrypted SSL network
           conversation could be recorded and subsequently decrypted.

PLATFORM:  HP9000 Series 7/800 running HP-UX releases 10.X and 11.00

DAMAGE:    A cryptanalytic vulnerability could potentially be used to
           discover the key for a particular encrypted session through
           a process of repeatedly sending approximately one million
           carefully constructed messages to a target server and
           observing the server's response.

SOLUTION:  Patches for can be downloaded from Netscape directly.
           See below for the URL.

AVAILABILITY:  All patches for 3.X servers are available now.  Older
           versions will be available soon.  For updated information
           on availability please check:

     http://help.netscape.com/products/server/ssldiscovery/index.html
-------------------------------------------------------------------------
I.
  A. Background

     According to RSA Data Security, Inc.,  this potential attack
     against secure Web communications is currently the subject of
     research and has not been reported by any users.

     CERT has made a technical advisory on this vulnerability available
     at  http://www.cert.org/


  B. Fixing the problem

     The following servers and products are affected.

     Servers impacted:
      FastTrack, Enterprise and Proxy.
       Patches are available for those three Servers.

     Messaging and Collabora.
      Product replacements are available for these two Servers.


  C. Recommended solution

     The URL is:
      http://help.netscape.com/products/server/ssldiscovery/index.html

     A README file is included with each package and has detailed
     instructions for installing the patch, for Enterprise and Proxy
     Server customer.  Please ensure you download the correct version.
     There is an international version (for customer outside US) as
     well as a domestic version (for customer within US and Canada).

     Netscape believes deployments with higher vulnerability are:

     FastTrack/Enterprise Server applications using SSL to protect
     communication of sensitive data over the Internet, Proxy servers
     in secure reverse proxy mode protecting sensitive communications,
     Messaging and Collabra Servers run exclusively in SSL mode over
     an unprotected network.

     HP recommends that products deployed in the above situations be
     updated as soon as is practical.
