The company has taken steps to address the newly-disclosed Heartbleed vulnerability by upgrading their OpenSSL libraries and replacing certificates, which may have exposed user data due to a bug in the OpenSSL library. To prevent unauthorized access to their Redis accounts, users are advised to change all passwords and certificates, following specific steps for each service provider, including Heroku, CloudFoundry, AppHarbor, and AppFog. The changes require updating config vars or configuration variables with new credentials, which may cause applications to restart. Users should take these precautions to protect their accounts and data from potential exploitation of the Heartbleed vulnerability.
