Description


Three security issues have been reported in IBM DB2, which can be exploited by malicious users to bypass certain security restrictions.

1) A security issue is caused due to an error in the application while revoking privileges on a database object from the "PUBLIC" group, which does not mark the dependent functions as "INVALID". This can lead to users with execute privileges on the functions still being able to call them successfully.

2) An error in the application while compiling a compound SQL statement with an "update" statement can be exploited by an unprivileged user to execute the query from the dynamic SQL cache.

3) An error in the db2updv97 tool when updating from Fix Pack 2 to Fix Pack 3 grants "EXECUTE" privileges to "PUBLIC" on the "SYSPROC.MON_GET_APPLICATION_HANDLE" and "SYSPROC.MON_GET_APPLICATION_ID" functions.

The security issues are reported in IBM DB2 9.7 prior to Fix Pack 3a running on AIX, HP-UX, Linux, Solaris, and Windows.


Solution:
Update to version 9.7 Fix Pack 3a.

Provided and/or discovered by:
Reported by the vendor.
