        HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0156, 2 July '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 setrlimit() allows incorrect core files
    
    PLATFORM: HP9000 Series 700/800 running HP-UX releases 10.01, 10.10,
              10.20, 10.24, 11.04, and 11.00 only.
    
    DAMAGE:   Possible denial of service
    
    SOLUTION: Install the appropriate patch for the HP-UX release:
                 11.11                          PHKL_23423,
                 11.04                          PHKL_23886,
                 11.00                          PHKL_23628,
                 10.20 700                      PHKL_22701,
                 10.20 800                      PHKL_22702,
                 10.24 700                      PHKL_24249,
                 10.24 800                      PHKL_24250,
                 10.10 700                      PHKL_23477,
                 10.10 800                      PHKL_23478,
                 10.01 700                      PHKL_23512,
                 10.01 800                      PHKL_23513.
    
    AVAILABILITY:  The patches are available now.
    -------------------------------------------------------------------------
       A. Background
          Hewlett-Packard has discovered that a process that at one time was
          setuid/setgid could create corefiles or be attached to with a
          debugger.  If the process core file's size limit has been set to 0
          in setrlimit(), when the process aborts, the core processing is
          incorrect.
    
       B. Recommended solution
          After applying this patch, the kernel now remembers that the
          process was at one time setuid/setgid, and disallow corefiles
          and debugger attachment.  If the process core file size limit
          has been set to zero, it obeys.
    
          Application of the appropriate patch selected from the list below
          completely solves this problem.
    
          For HP-UX release:
                 11.11                          PHKL_23423,
                 11.04                          PHKL_23886,
                 11.00                          PHKL_23628,
                 10.20 700                      PHKL_22701,
                 10.20 800                      PHKL_22702,
                 10.24 700                      PHKL_24249,
                 10.24 800                      PHKL_24250,
                 10.10 700                      PHKL_23477,
                 10.10 800                      PHKL_23478,
                 10.01 700                      PHKL_23512,
                 10.01 800                      PHKL_23513.
    
          Note: Many of these patches have dependencies.  A reboot will
                be required.
