Description


Some vulnerabilities has been reported in DB2, which can be exploited by malicious people and users to cause a DoS (Denial of Service).

1) A boundary exists within the handling of a CONNECT or ATTACH request. This can be exploited to cause a buffer overflow, which crashes the database instance, via a malicious request sent to a DB2 server.

2) An error exists within the handling of the LOAD command. This can be exploited to cause stack corruption, which crashes the database instance, via a specially crafted LOAD command with an overly long column list specified in the REPLACE INTO or INSERT INTO sections.

3) An error exists within the handling of incorrect package information sent from a downlevel client. This can be exploited to crash the server via specially crafted package information sent from a client.

4) An error exists within the handling of a query that contains large number of values in the IN clause and can be exploited to crash the database instance.

Note: Several other issues that may be security related have also been fixed.


Solution:
The vulnerabilities have been fixed in Version 8 FixPak 12 (Version 8.2 FixPak 5).
