DB2 - Problem description

Problem IC71263 Status: Closed

SECURITY: User continues to have privilege to execute a non-DDL statement
after role membership has been revoked from its group

product:
DB2 FOR LUW / DB2FORLUW / 950 - DB2
Problem description:
If a user successfully execute a non-DDL statement, and the 
needed privileges are inherited through role membership (with 
the role granted to the user's group), then after the role was 
revoked from the group, the user can still execute the same 
statement where the statement has already completed the 
authorization checking. The user will continue to be able to 
re-execute this same statement until they disconnect from the 
database or attempt to execute another statement.
