Popular custom ROM developers CyanogenMod team has released the new Android 4.4.4 KitKat CM11 M12 milestone series firmware update to the Samsung's 2013 compact flagship smartphone Galaxy S4 Mini 3G model.

Like all software updates, CM11 M12 series too brings some enhancements to battery life, performance, but one key improvement in this latest CyanogenMod milestone firmware is that, it fixes the POODLE vulnerability found in SSL (Secure Socket Layer) v3 protocol, which is used by almost all Internet browsers found in Android devices.

This loophole in the internet protocol gave leeway for hackers to cause connection failures and trigger the use of SSL 3.0. Hackers exploited this to steal sensitive data from Android devices. [More information, HERE]
