Description
Red Hat OpenShift Container Platform is the company's cloud computing Platform-as-a-Service (PaaS) solution designed for on-premise or private cloud deployments.
This advisory contains RPM packages for this release. See the following advisory for the container images for this release:
https://access.redhat.com/errata/RHBA-2018:1232
Security Fix(es):
- source-to-image: Improper path sanitization in ExtractTarStreamFromTarReader in tar/tar.go (CVE-2018-1102)
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)
