(RHSA-2012:1168) Important: condor security update

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 (i.e.
actions requiring ALLOW_ADMINISTRATOR or ALLOW_WRITE). Condor deployments
using host-based authentication that contain no hostnames (IPs or IP globs
only) or use authentication stronger than host-based are not vulnerable.
(CVE-2012-3416)

Note: Condor will not run jobs as root; therefore, this flaw cannot lead to
a compromise of the root user account.

Red Hat would like to thank Ken Hahn and Dan Bradley for reporting this
issue.

All Red Hat Enterprise MRG 2.1 users are advised to upgrade to these
updated packages, which contain a backported patch to correct this issue.
Condor must be restarted for the update to take effect.
