IBM DB2 Universal Database
A Denial of Service (DoS) condition exists in IBM's DB2 Universal Database. IBM DB2's UDP-based discovery service, listening on port 523, shut downs when it receives more than 20 bytes of data. After the discovery service crashes, the service requires a restart.
IBM has released FixPak 10a to address this vulnerability.
