As for the security updates, this is what Google has to say about the issues labeled as high or critical:
The most severe of these issues is a critical security vulnerability in Media framework that could enable a remote attacker using a specially crafted file to execute arbitrary code within the context of a privileged process. The severity assessment is based on the effect that exploiting the vulnerability would possibly have on an affected device, assuming the platform and service mitigations are turned off for development purposes or if successfully bypassed.
We have had no reports of active customer exploitation or abuse of these newly reported issues.
