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.
MANUAL ACTIONS: Install replacement rpc.ttdbserver.
AVAILABILITY: The replacement rpc.ttdbserver files are
available now.
------------------------------------------------------------------
A. Background
A buffer overflow in rpc.ttdbserver has been reported by CERT
in CA-2002-20. It may be possible to exploit this overflow to
gain unauthorized access.
B. Recommended solution
Until patches are available, install the appropriate file to
replace rpc.ttdbserver.
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.
System: hprc.external.hp.com (192.170.19.51)
Login: ttdb1
Password: ttdb1
FTP Access: ftp://ttdb1:tt...@hprc.external.hp.com/
or: ftp://ttdb1:tt...@192.170.19.51/
file: rpc.ttdbserver.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.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) = da1be3aaf70d0e2393bd9a03feaf4b1d
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.tar.gz.
For example on a 10.20 system:
./install_rpc.ttdbserver rpc.ttdbserver.1020
