CVE-2009-4326: Infoleak
First published: Wed Dec 16 2009(Updated: )
The RAND scalar function in the Common Code Infrastructure component in IBM DB2 9.5 before FP5 and 9.7 before FP1, when the Database Partitioning Feature (DPF) is used, produces "repeating" return values, which might allow attackers to defeat protection mechanisms based on randomization by predicting a value.
