10.20, 10.24, 11.00, 11.04, and 11.11.
DAMAGE: Potential unauthorized access, increased privileges.
SOLUTION: Until patches are available, manually install a

------------------------------------------------------------------
**REVISED 02**
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.
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.
**REVISED 02**
-->> 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.
