Synopsis:    Low: rgmanager security, bug fix, and enhancement update
Issue Date:  2011-07-21
CVE Numbers: CVE-2010-3389


The rgmanager package contains the Resource Group Manager, which
provides the ability to create and manage high-availability server
applications in the event of system downtime.

It was discovered that certain resource agent scripts set the
LD_LIBRARY_PATH environment variable to an insecure value containing 
empty path elements. A local user able to trick a user running those 
scripts to run them while working from an attacker-writable directory 
could use this flaw to escalate their privileges via a specially-crafted 
dynamic library. (CVE-2010-3389)

This update also fixes the following bugs:

* The failover domain "nofailback" option was not honored if a service 
was in the "starting" state. This bug has been fixed.

* PID files with white spaces in the file name are now handled correctly.

* The /usr/sbin/rhev-check.sh script can now be used from within Cron.

* The clustat utility now reports the correct version.

* The oracledb.sh agent now attempts to try the "shutdown immediate"
command instead of using the "shutdown abort" command.

* The SAPInstance and SAPDatabase scripts now use proper directory name
quoting so they no longer collide with directory names like "/u".

* The clufindhostname utility now returns the correct value in all cases.

* The nfsclient resource agent now handles paths with trailing slashes
correctly.

* The last owner of a service is now reported correctly after a failover.

* The /usr/share/cluster/fs.sh script no longer runs the "quotaoff" 
command if quotas were not configured.

* The "listen" line in the /etc/httpd/conf/httpd.conf file generated by 
the Apache resource agent is now correct.

* The tomcat-5 resource agent no longer generates incorrect configurations.


* The time required to stop an NFS resource when the server is 
unavailable has been reduced.

* When using exclusive prioritization, a higher priority service now
preempts a lower priority service after status check failures.

* The postgres-8 resource agent now correctly detects failed start
operations.

* The handling of reference counts passed by rgmanager to resource 
agents now works properly, as expected.

As well, this update adds the following enhancements:

* It is now possible to disable updates to static routes by the IP 
resource agent.

* It is now possible to use XFS as a file system within a cluster service.

* It is now possible to use the "clustat" command as a non-root user, so
long as that user is in the "root" group.

* It is now possible to migrate virtual machines when central processing 
is enabled.

* The rgmanager init script will now delay after stopping services in 
order to allow time for other nodes to restart them.

* The handling of failed independent subtrees has been corrected.

All users of Resource Group Manager are advised to upgrade to this
updated package, which contains backported patches to correct these 
issues and add these enhancements.
