CVE-2018-17419

The Miek Gieben DNS library is vulnerable to a denial of service caused by a segmentation violation in setTA in scan_rr.go. By persuading a victim to open a specially-crafted file, a remote attacker can cause the application to crash.

The opportunity for a denial of service is limited to the golang runtime. In the case of the OpenShift Container Platform, this would be restricted within each individual container. There are multiple layers of guide rails (Golang’s Garbage Collector; OpenShift’s resource constraints imposed at the container and cluster levels) which would require a malicious user to continue submitting attacks for there to be any enduring impact. They would also need access to external server resources to be able to send a massive volume of requests to cause a significant impact on server operations.
