Vulnerability 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 theVersions 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 issue, if DNS recursion is not required, you can disable recursion in the BIND configuration.
Additionally, when DNS recursion is required, you can limit exposure to the vulnerability by configuring an ACL to restrict DNS recursion to trusted users. For more information, refer to SOL7055: Enabling DNS recursion in the named configuration on a BIG-IP GTM system.
