CVE-2007-5324

-- Affected Vendor:

IBM

DB2 Universal Database 8.1

DB2 Universal Database 8.2

-- 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
