Security Bulletin: Buffer Overflow Vulnerability in IBM DB2 Java Stored Procedure Infrastructure (CVE-2012-2197).
Vulnerability in IBM DB2 could allow an authenticated user to cause a stack-based buffer overflow and possibly attain remote code execution.
CVE ID: CVE-2012-2197
The IBM DB2 products listed below contain a security vulnerability that could
allow an authenticated user to exploit a vulnerability in DB2's Java Stored Procedure infrastructure to cause a stack-based buffer overflow and possibly attain remote code
To exploit the vulnerability the malicious user would need:
1. Valid credential to connect to database
2. CONNECT privilege on database
3. A Java stored procedure to which the user has EXECUTE privilege.
If you do not have any Java stored procedures installed then you are not affected. To find the names of your Java stored procedures, execute the following SQL statement using the DB2 Command Line Processor (CLP):
SELECT ROUTINENAME FROM SYSCAT.ROUTINES WHERE LANGUAGE='JAVA'
If you have no Java stored procedures installed then you would get back an empty result like the following:
