Summary

HTCondor 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.
A denial of service flaw was found in the way HTCondor's policy definition evaluator processed certain policy definitions. If an administrator used an attribute defined on a job in a CONTINUE, KILL, PREEMPT, or SUSPEND condor_startd policy, a remote HTCondor service user could use this flaw to cause condor_startd to exit by submitting a job that caused such a policy definition to be evaluated to either the ERROR or UNDEFINED states. (CVE-2013-4255)
Note: This issue did not affect the default HTCondor configuration.
This issue was found by Matthew Farrellee of Red Hat.
All Red Hat Enterprise MRG 2.3 users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. HTCondor must be restarted for the update to take effect.
