Category:  Application (Generic)  >  ToolTalk (rpc.ttdbserver) Vendors:  HP
(HP Issues Workaround) Re: ToolTalk Database Server Format String Flaw Lets Remote Users Gain Root Level Privileges on Several UNIX Operating System Platforms
Updated:  Oct 3 2001
Original Entry Date:  Oct 3 2001
Impact:  Execution of arbitrary code via network, Root access via network
Fix Available:  Yes   Vendor Confirmed:  Yes  
Version(s): HP9000 Series 700/800 running HP-UX releases 10.10, 10.20, 11.00, and 11.11.
Description:  HP warned of a buffer overflow vulnerability in the HP-UX ToolTalk database server (rpc.ttdbserver) that could allow remote users to obtain root level access on the server.

Because the process runs with root level privileges, a remote user can exploit the buffer overflow to cause arbitrary code to be executed with root level privileges, giving the remote user root level access to the server.

HP reports that the rpc.ttdbserver process is not needed for the programs provided in HP's CDE product but may be needed by third party applications using ToolTalk.

Impact:  A remote user can execute arbitrary code on the server with root leve privileges, yielding root level access on the server.
Solution:  No patches were available at the time of this entry. The vendor recommends that users install a replacement rpc.ttdbserver file or disable the rpc.ttdbserver until patches are available. The replacement rpc.ttdbserver files are available now.

As noted in the Source Message, the vendor's recommended solution is to perform the following steps:

"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
itrc.hp.com.

ftp site: hprc.external.hp.com (192.170.19.51).
account: xgraphic
password: xgraphic
directory: ~xgraphic/CDE
file: rpc.ttdbserver.tar.gz

If using a browser:

ftp://xgraphic:xgraphic@hprc.external.hp.com//xgraphic/CDE

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:

HPSBUX9408-016
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 [a Readme file]"

Vendor URL:  www.hp.com/ (Links to External Site)
Cause:  Input validation error
Underlying OS:  UNIX (HP/UX)
Reported By:  support_feedback@us-support.external.hp.com (IT Resource Center )

      Title:  Sec. Vulnerability in rpc.ttbdserver

---------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0168,
    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
               now.

 ------------------------------------------------------------------
I.
 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
         itrc.hp.com.

          ftp site: hprc.external.hp.com (192.170.19.51).
          account: xgraphic
          password: xgraphic
          directory: ~xgraphic/CDE
          file: rpc.ttdbserver.tar.gz

           If using a browser:

           ftp://xgraphic:xgraphic@hprc.external.hp.com//xgraphic/CDE

           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:

               HPSBUX9408-016
               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:
