Problem Description:

Updated condor packages that fix a security issue and several bugs are now available for Red Hat Enterprise MRG.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

2. Relevant releases/architectures:

MRG Grid for RHEL 5 Server - i386, x86_64

3. Description:

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.

A flaw was found in the way Condor interpreted wildcards in authorization lists. Certain authorization lists using wildcards in DENY rules, such as DENY_WRITE or HOSTDENY_WRITE, that conflict with the definitions in ALLOW rules, could permit authenticated remote users to submit computation jobs, even when such access should have been denied. (CVE-2008-3424)

Bug fixes:

* the /etc/condor/condor_config file started with "What machine is your central manager?". The following line was blank, instead of having the "CONDOR_HOST" option, causing confusion. The "What machine..." text is now removed.

* condor_config.local defined "LOCK = /tmp/[lock file]". This is no longer explicitly defined; however, lock files may be in "/tmp/", and could be removed by tmpwatch. A "LOCK_FILE_UPDATE_INTERVAL" option, which defaults to eight hours, has been added. This updates the timestamps on lock files, preventing them from being removed by tools such as tmpwatch.

* when a "SCHEDD_NAME" name in condor_config ended with an "@", the system's hostname was appended. For example, if "SCHEDD_NAME = test@" was configured, "condor_q -name test@" failed with an "Collector has no record of schedd/submitter" error. Now, the hostname is not appended when a name ends with an "@". In High Availability (HA) Schedd deployments, this allows a name to be shared by multiple Schedds.

* when too few arguments were passed to "condor_qedit", such as "condor_qedit -constraint TRUE", a segfault occurred. Better argument handling has been added to resolve this.

* due to missing common_createddl.sql and pgsql_createddl.sql files, it was not possible to use Quill. Now, these files are included in "/usr/share/condor/sql/".

* "condor_submit -dump ad [file-name]" caused a segfault if the [file-name] job contained "universe = grid".

* previously, a condor user and group were created if they did not exist, without specifying a specific UID and GID. Now, UID and GID 64 are used. The effect of this change is non-existent if upgrading the condor packages. If an existing condor user and group are manually changed, problems with file ownership will occur.

Configuration changes (from the Condor release notes - see link below):

* a new CKPT_SERVER_CHECK_PARENT_INTERVAL variable sets the time interval between a checkpoint server checking if its parent is running. If the parent server has died, the checkpoint server is shut down.

* a new CKPT_PROBE variable to define an executable for the helper process Condor uses for information about the CheckpointPlatform attribute.

* STARTER_UPLOAD_TIMEOUT now defaults to 300 seconds.

* new variables (booleans) PREEMPTION_REQUIREMENTS_STABLE and PREEMPTION_RANK_STABLE, configure whether attributes used in PREEMPTION_REQUIREMENTS and PREEMPTION_RANK change during negotiation cycles.

* a new GRIDMANAGER_MAX_WS_DESTROYS_PER_RESOURCE variable, with a default value of 5, defines the number of simultaneous WS destroy commands that can be sent to a server for type gt4 grid universe jobs.

* now, VALID_SPOOL_FILES automatically includes the "SCHEDD.lock" lock file for condor_schedd HA failover.

* the default value for SEC_DEFAULT_SESSION_DURATION has been changed from 8640000 seconds (100 days) to 86400 seconds (one day).

Important: these updated packages upgrade Condor to version 7.0.4. For a full list of changes, refer to the Condor release notes: www.cs.wisc.edu/condor/manual/v7.0/8_3Stable_Release.html

condor users should upgrade to these updated packages, which resolve these issues.
