What is CVE-2015-9259?

The Docker Notary service prior to version 0.1 contains a vulnerability where the checkRoot function fails to validate the expiry of root.json files. This oversight creates a security risk, allowing an attacker to exploit situations where a user may have updated their root.json file following a key compromise. Instead of recognizing the updated file, the system may still accept update files tied to the previously compromised root.json file. This can lead to unauthorized modifications and undermine the integrity of the Docker Notary system.
