Red Hat Security Advisory 2012-1168-01 - Condor is a specialized workload management system for compute-intensive jobs. It provides a job queuing mechanism, scheduling policy, priority scheme, and resource monitoring and management. Condor installations that rely solely upon host-based authentication were vulnerable to an attacker who controls an IP, its reverse-DNS entry and has knowledge of a target site's security configuration. With this control and knowledge, the attacker could bypass the target site's host-based authentication and be authorized to perform privileged actions. Condor deployments using host-based authentication that contain no hostnames or use authentication stronger than host-based are not vulnerable.
