- -- CVE ID:
CVE-2007-5324
- -- Affected Vendor:
IBM
- -- Affected Products:
DB2 Universal Database 8.1
DB2 Universal Database 8.2
- -- TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability since January 5, 2007 by Digital Vaccine protection
filter ID 4870,4876,4877. For further product information on the
TippingPoint IPS:

- -- 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
vulnerabilities.
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
terminate.
- -- Vendor Response:
IBM has issued an update to correct this vulnerability. More details can
