AVAILABILITY: The replacement rpc.ttdbserver files are
available now.
CHANGE SUMMARY: Added CA-2002-26 information
------------------------------------------------------------------
**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.

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