RHSA-2015:0035 - Security Advisory

Topic

Updated condor packages that fix one security issue are now available for
Red Hat Enterprise MRG 2.5 for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

Description

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.

The HTCondor scheduler can optionally notify a user of completed jobs by
sending an email. Due to the way the daemon sent the email message,
authenticated users able to submit jobs could execute arbitrary code with
the privileges of the condor user. (CVE-2014-8126)

This issue was discovered by Florian Weimer of Red Hat Product Security.

All Red Hat Enterprise MRG 2.5 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.
