* Upgrading an affected system to a fixed version will not eliminate any
existing exposure. In addition to upgrading to a fixed version, you should also
perform the mitigation steps listed in the following Security Advisory
Recommended Actions section.

Security Advisory Recommended Actions

If you are running a version listed in the Versions known to be vulnerable
column, you can eliminate this vulnerability by upgrading to a version listed
in the Versions known to be not vulnerable column. If the table lists only an
older version than what you are currently running, or does not list a
non-vulnerable version, then no upgrade candidate currently exists.

To mitigate this vulnerability, you can remove any affected messages from the /
var/log/ltm log file that appear similar to the following examples:

/bin/sh /usr/bin/safenet-sync.sh -p <PASSWORD> ==> /usr/bin/bigstart restart
pkcs11d
/bin/sh /usr/bin/safenet-sync.sh -p <PASSWORD> ==> /usr/bin/bigstart restart
tmm
/bin/sh /usr/bin/safenet-sync.sh -p <PASSWORD> ==> /usr/bin/bigstart restart
pkcs11d
/bin/sh /usr/bin/safenet-sync.sh -p <PASSWORD> ==> /usr/bin/bigstart restart
tmm

In addition to the current /var/log/ltm file, you should also delete or scrub
any ltm log files that have been rotated (ltm.1.gz, ltm.2.gz,etc.), and any
other files that may contain affected ltm log files, such as qkview files, or
log files that have been backed up to an alternate location.

Important: If you believe the password may have been compromised, you can
change the password on the Safenet HSM device and in the BIG-IP configuration.
To do so refer to K16350062: Changing the SafeNet HSM partition password.
