https://access.redhat.com/errata/RHBA-2018:1232

Security Fix(es):

This update also fixes the following bugs:

• Image validation used to validate old image objects, and an invalid image could be pushed to etcd. With this bug fix, validation has been changed to validate new image objects, and as a result it is no longer possible to upload an invalid image object. (BZ#1559982)
• A panic could occur due to concurrent writes to cache. This bug fix protects writes to the cache with mutex. As a result, the cache is safe to use concurrently. (BZ#1549916)
