Workarounds and Mitigations

Install the fix pack by running the installation wizard or by running a silent installation:
To avoid an untrusted search path vulnerability where users could gain increased privileges, perform the following additional steps:
1. Clear all contents (files, sub-directories and etc.,) of your default download directory/location, if any.
2. Create a new secure directory in temporary location (such that elevated privileges are required to access this directory).
3. Copy the DB2 fix pack install image executable to the secure directory created in Step 2.
4. Launch the executable from the secure directory and wait until it completes.

Important: Do not enter line breaks in the command that you enter to start the installation program.
