Problem IC97480
|
Status: Closed |
CLIENT LOAD CAN FAIL DUE TO MEMORY OVERWRITE BECAUSE OF INCORRECT INPUT PARSING |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
A client side load will send the data and some conrol
information across to the server using the DRDA communication
protocol.
In very rare circumstances, it is possible that a split DRDA
message is wrongly interpreted by the DB2 server.
This then leads to the load code wrongly interpreting a length
which can trigger a large memory overwrite.
As the overwrite can be large in size, the EDU detecting the
problem is likely not the one causing the problem, so a stack
will not directly point to this problem.
The key factor leading to this problem is that a ( large )
client side load was happening at the time of the problem. |
