      Title:  Sec. Vulnerability in Text editors

- ----------------------------------------------------------------------
   HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0140, 14 Feb. '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.
- ----------------------------------------------------------------------
ISSUE:     Text editors contain a buffer overflow.

PLATFORM:  HP9000 Series 700 and 800 running HP-UX releases 11.00,
           11.04, 10.20, 10.24, 10.10, and 10.01.

POSSIBLE RESULT: Users could compromise system availability.

SOLUTION: Apply patches for HP-UX releases as follows:
                 for 11.00:           PHCO_22229,
                     11.04:           PHCO_23354,
                     10.20:           PHCO_22228,
                     10.24:           PHCO_23353,
                     10.10:           PHCO_22848,
                     10.01:           PHCO_22849.

AVAILABILITY: The patches are available now.
- -----------------------------------------------------------------------
I.
    A. Background
       Hewlett-Packard Company has become aware of a defect in the
       text editor, in various releases of the HP-UX OS.  This defect
       affects various programs such as e, ex, vi, edit, view, and
       vedit which all use the same facilities.

    B. Fixing the problem
       The problem can be fully resolved by applying the appropriate
       patches to the system. For HP-UX releases
                 for 11.00:           PHCO_22229,
                     11.04:           PHCO_23354,
                     10.20:           PHCO_22228,
                     10.24:           PHCO_23353,
                     10.10:           PHCO_22848,
                     10.01:           PHCO_22849.

       While this patch does not require a reboot, appropriately
       terminating any instances of editor before installation of the
       patch will assure that continued operation is now done with
       the patched binaries.
