https://access.redhat.com/errata/RHBA-2018:1230

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 :

* Fluentd inserts documents (logs) into Elasticsearch using the bulk insert API, but relies upon Elasticsearch to generate UUIDs for each document. It does not remove successfully indexed documents from the bulk payload when the bulk operation fails. This caused the initial payload to be resubmitted and documents that were successfully indexed to be submitted again, which results in duplicate documents with different UUIDs. This bug fix ensures that document IDs are generated before submitting bulk insert requests. As a result, Elasticsearch will disregard the insertion of documents that already exist in the data store and insert documents that do not. (BZ# 1556896)

* A user can set a host name to `localhost`, which confuses the router check to see if the reload completed. This caused the reload to never return success, causing the router to fail. This bug fix changes the health check so that it does not pass the host name `localhost`. As a result, routers can now reload successfully. (BZ#1548102)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
