                Rev.04 Patch available for 11.00.

 ------------------------------------------------------------------ 
 A. Background
    Buffer overflows in rpc.ttdbserver has been reported by CERT
    in CA-2002-20 and CA-2002-26.  The potential exists to exploit
    these overflows to gain unauthorized access.

 B. Recommended solution
    Until patches are available, install the appropriate file to
    replace rpc.ttdbserver.

**REVISED 04**
     For 10.20 install PHSS_27426.
     For 11.00 install PHSS_27427.
 -->>For 11.11 install PHSS_27428.

     Note: The 10.20 file should be used for 10.24.
           The 11.00 file should be used for 11.04.

           On 10.24 and 11.04 (VVOS) rpc.ttdbserver is disabled
           by default.

      1. Download rpc.ttdbserver.2.tar.gz from the ftp site.
         This file is temporary and will be deleted when patches
         are available from the standard HP web sites, including
         itrc.hp.com.

        System:    hprc.external.hp.com  (192.170.19.51)
        Login:     ttdb1
        Password:  ttdb1

        FTP Access: ftp://ttdb1:ttdb1@hprc.external.hp.com/
               or: ftp://ttdb1:ttdb1@192.170.19.51/

        file: rpc.ttdbserver.2.tar.gz

        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

      2. Copy the rpc.ttdbserver.2.tar.gz file to a protected
         directory and unpack it.
         If you wish to verify the md5 sum before unpacking the
         rpc.ttdbserver.tar.gz file, please refer to:

               HPSBUX9408-016
               Patch sums and the MD5 program

          The md5 sum for rpc.ttdbserver.2.tar.gz is:

      MD5 (rpc.ttdbserver.2.tar.gz) =
                     e6af458213a9834146f716c9df7f1aaf

      3. Install the new rpc.ttdbserver file using the
         install_rpc.ttdbserver script or some similar procedure.
         The install_rpc.ttdbserver script is included in
         rpc.ttdbserver.2.tar.gz.

         For example on a 10.20 system:

            ./install_rpc.ttdbserver rpc.ttdbserver.1020
