      Title:  Sec. Vulnerability in rpc.ttbdserver

- ---------------------------------------------------------------
    Originally issued: 01 October '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:  Buffer overflow in rpc.ttdbserver

PLATFORM: HP9000 Series 700/800 running HP-UX releases 10.10,
          10.20, 11.00, and 11.11.

DAMAGE:  Unauthorized access, increased privileges.

SOLUTION: Until patches are available manually install a replacement
          rpc.ttdbserver file or disable rpc.ttdbserver.

MANUAL ACTIONS: Install a replacement rpc.ttdbserver file or
                disable rpc.ttdbserver.

AVAILABILITY:  The replacement rpc.ttdbserver files are available

 A. Background
      A remotely exploitable buffer overflow in rpc.ttdbserver has
      been reported to HP.

 B. Fixing the problem
      Until patches are available install the appropriate file
      to replace rpc.ttdbserver.  Another alternative is to disable
      rpc.ttdbserver.  The rpc.ttdbserver process is not needed for
      the programs provided in HP's CDE product.  It may be needed
      by third party applications using ToolTalk.  If you are not
      using ToolTalk applications rpc.ttdbserver may be disabled.

         chmod 444 /usr/dt/bin/rpc.ttdbserver

 C. Recommended solution

      1. Download rpc.ttdbserver.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

          ftp site: hprc.external.hp.com (
          account: xgraphic
          password: xgraphic
          directory: ~xgraphic/CDE
          file: rpc.ttdbserver.tar.gz

           If using a browser:


           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.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:

               Patch sums and the MD5 program

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

         MD5 (rpc.ttdbserver.tar.gz) = 64ad589ec6dd55dceea2c92dc9ae9c19

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

         For example on a 10.20 system:

            ./install_rpc.ttdbserver rpc.ttdbserver.10.20

      4. The rpc.ttdbserver.tar.gz includes the rpc.ttdbserver files,
         the install_rpc.ttdbserver script, and the following:

Note:  This site
is temporary and will be deleted when official patches are available.

The install_rpc.ttdbserver script may be used to install the
special release versions of rpc.ttdbserver.

As root set the working directory to the location of the
special release rpc.ttdbserver files and

   ./install_rpc.ttdbserver <rpc.ttdbserver.xx.yy>
