A Vulnerability Was Found In Several Of Our DEV Tools So Please Update

I received an email on August 2nd, 2018 regarding updating due to the vulnerability. I purchased the Theme Version: Catalyst 1.5.4 Child Theme Version: Dynamik 1.1. back in 2011. I have built several sites and they are now having some strange things occuring. My question is are there updates for these older Cobolt Apps and is there any other information that I may have missed since purchasing these app back in 2011? Thank you in advance for any assistance!
