Who is Vulnerable?
Vulnerability Description IBM DB2 Database is a relational database management system that includes the DB2 Administration Server (DAS) service. The DB2 Administration Server (DAS) assists the Control Center and Configuration Assistant in enabling remote administration of DB2 database instances, providing the facility for job management, defining the scheduling of jobs, viewing the results of completed jobs, providing a means for discovering information about the configuration of DB2 instances, databases, and other DB2 administration servers in conjunction with the DB2 Discovery utility. A heap buffer overflow vulnerability has been discovered in IBM DB2 Universal Database. The vulnerability is due to insufficient bound checking on a user-supplied buffer length value in a receiveDASMessage message. A remote attacker can exploit this issue by providing a malicious buffer length in a receiveDASMessage message. Successful exploitation of this vulnerability could result in arbitrary code execution on an affected system.
