Updated: Oct 13 2007|
Original Entry Date: Oct 11 2007
Denial of service via network, Execution of arbitrary code via network, User access via network|
Fix Available: Yes Vendor Confirmed: Yes |
Version(s): 8.1, 8.2|
Two vulnerabilities were reported in DB2. A remote user can execute arbitrary code on the target system. A remote user can cause denial of service conditions.|
A remote user can send specially crafted data to the DB2JDS service on TCP port 6789 to trigger a stack overflow and execute arbitrary code on the target system. The code will run with the privileges of the target service.
A remote user can send a specially crafted LANG parameter value or a packet length over 32768 bytes to cause the target service to crash.
The vendor was notified on November 9, 2006.
TippingPoint reported this vulnerability.

-- Vulnerability Details:
The most severe of these vulnerabilities allows remote attackers to
execute arbitrary code on vulnerable installations of IBM DB2 Universal
Database. Authentication is not required to exploit these
The first flaw exists in the DB2JDS service listening on TCP port 6789.
A specially crafted packet is improperly processed by an internal
sprintf() call resulting in a stack overflow which can be leveraged to
execute arbitrary code.
Additionally, two DoS condition vulnerabilities were discovered. The
first flaw is an overflow resulting from an invalid LANG paramater. The
second DoS can be triggered by sending a packet over 32768 bytes in
length, resulting in a MemTree overflow which will cause the process to
