o Security Bulletin Digest Split
   ------------------------------

   The security bulletins digest has been split into multiple digests
   based on the operating system (HP-UX, MPE/iX, and HP Secure OS
   Software for Linux). You will continue to receive all security
   bulletin digests unless you choose to update your subscriptions.
   
   To update your subscriptions, use your browser to access the
   IT Resource Center on the World Wide Web at:

     http://support.itrc.hp.com/

   Under the Maintenance and Support Menu, click on the "more..." link.
   Then use the 'login' link at the left side of the screen to login
   using your IT Resource Center User ID and Password.

   Under the notifications section (near the bottom of the page), select
   Support Information Digests.

   To subscribe or unsubscribe to a specific security bulletin digest,
   select or unselect the checkbox beside it. Then click the
   "Update Subscriptions" button at the bottom of the page.

 A. Background

    The SSRT thanks Davide Del Vecchio for
    reporting this potential vulnerability to HP.

    HP Tru64 UNIX is not vulnerable to this reported problem.

 B. Recommended solution

    11.00 - Install PHCO_24723 or subsequent. PHCO_24723 has been
            superseded. To find the recommended superseding patch
            and the latest superseding patch, search the technical
            knowledge base on itrc.hp.com for "PHCO_24723".

    10.20 - Download and install libc.1.10.20 as described below.

    Note: This libc.1.10.20 also has the fixes for the potential
          vulnerabilities mentioned in HPSBUX0208-209 and
          HPSBUX0303-252.

     System: hprc.external.hp.com (192.170.19.51)

     Browser ftp access:

       ftp://rexec:rexechprc.external.hp.com/
       ftp://rexec:rexec192.170.19.51/

        Note: There is an ftp defect in IE5 that may result in
               a browser hang. To work around this:
        Select Tools -> Internet Options -> Advanced
        Un-check the option: [ ] Enable folder view for FTP sites

         If you wish to verify the md5 sum please refer to:

               HPSBUX9408-016
               Patch sums and the MD5 program

     Download libc.1.10.20.gz and unpack with gunzip.

     Verify the cksum or md5 sum.

     cksum:
     2506697268 1867776 libc.1.10.20

     MD5 (libc.1.10.20) = cabd081cee3e980d7f3075bb7c6a505d

     Go to init state 2

      #DIR=[path to new libc.1]

      #cd /usr/lib
      #cp libc.1 libc.1.orig
      #cp $DIR/libc.1.10.20 libc.1.new
      #chown bin libc.1.new
      #chgrp bin libc.1.new
      #chmod 555 libc.1.new
      #/sbin/mv libc.1 was.libc.1

    listed in the Security Patch Matrix will completely
    implement a security bulletin _only_ if the MANUAL ACTIONS
    field specifies "No."

    bulletin has been implemented on HP-UX 11.XX systems providing
    that the fix is completely implemented in a patch with no
    manual actions required. The Security Patch Check tool cannot
    verify fixes implemented via a product upgrade.
