Session Validation attacks in Apache Superset versions up to and including 2.0.1. Installations that have not altered the default configured SECRET_KEY according to installation instructions allow for an attacker to authenticate and access unauthorized resources. This does not affect Superset administrators who have changed the default value for SECRET_KEY config.
All superset installations should always set a unique secure random SECRET_KEY. Your SECRET_KEY is used to securely sign all session cookies and encrypting sensitive information on the database.
Add a strong SECRET_KEY to your `superset_config.py` file like:
SECRET_KEY = <YOUR_OWN_RANDOM_GENERATED_SECRET_KEY>
Alternatively you can set it with `SUPERSET_SECRET_KEY` environment variable.
Linux Kernel 2.x-4.x < 4.8.3 - Local Privilege Escalation via Dirty COW Race Condition
Race condition in mm/gup.c in the Linux kernel 2.x through 4.x before 4.8.3 allows local users to gain privileges by leveraging incorrect handling of a copy-on-write (COW) feature to write to a read-only memory mapping, as exploited in the wild in October 2016, aka "Dirty COW."
