      Title:  Sec. Vulnerability in inetd(1M)

------------------------------------------------------------------------
     HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #00136, 09 Jan. '01
------------------------------------------------------------------------

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 inet server (inetd) on HP-UX can be hung by malicious
          users.

PLATFORM: HP 9000 servers running HP-UX releases 10.20, 10.24, 11.00,
          and 11.04.

DAMAGE:   Possible Denial of Service (DoS).

SOLUTION: Install the appropriate patch as noted below:
              PHNE_20747 for HP-UX release 10.20; or
              PHNE_21699 for VVOS release  10.24; or
              PHNE_21835 for HP-UX release 11.00; or
              PHNE_23068 for VVOS release 11.04.

AVAILABILITY:  The patches are available now.
------------------------------------------------------------------------
I.
   A. Background
      A server that uses the 'swait' state in the /etc/inetd.conf file
      can be made to interfere with one or more services started by
      inetd.  This affects only installations where configuration
      alterations have been done to include 'swait' service entries.
      The standard configuration of the Internet Services product,
      InternetSrvcs, provided by Hewlett-Packard, including telnetd,
      ftpd, rlogind, etc., will not exhibit the behavior in question.

B. Recommended solution
      The problem can be rectified by installing one of the following
      patches. PHNE_20747 for HP-UX release 10.20; or
               PHNE_21699 for VVOS release  10.24; or
               PHNE_21835 for HP-UX release 11.00; or
               PHNE_23068 for HP-UX release 11.04.
