      Title:  Security Vulnerability with SharedX


The information in the following Security Bulletin 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 Bulletin as soon as possible.

PROBLEM:  The SharedX program recserv is vulnerable to a denial of
          service attack.

PLATFORM:  HP 9000 series 700/800.

DAMAGE:    Excessive cpu usage.

SOLUTION:  Install the patches listed below.

AVAILABILITY:  All patches are available now.

   A. Background
      HP SharedX Receiver Service (recserv) provides a method for a
      receiver to allow the sharing of windows without explicitly
      performing any xhost commands.  The Internet daemon, inetd,
      executes recserv when it receives a service request at the port
      listed in the services database.  Certain messages to the port
      can cause recserv to enter a tight processing loop

   B. Fixing the problem - Install the applicable patch:

         HP-UX revision 10.01  HP9000 Series 7/800   PHSS_16646
         HP-UX revision 10.10  HP9000 Series 7/800   PHSS_16647
         HP-UX revision 10.20  HP9000 Series 7/800   PHSS_16648
         HP-UX revision 11.00  HP9000 Series 7/800   PHSS_16649

      Note - For HP-UX revisions prior to 10.01, update to 10.X,
             or 11.X and install the applicable patch.
