Topic

An updated rgmanager package that fixes one security issue, several bugs,
and adds multiple enhancements is now available for Red Hat Enterprise
Linux 5.

The Red Hat Security Response Team has rated this update as having low
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

The rgmanager package contains the Red Hat 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)

Red Hat would like to thank Raphael Geissert for reporting this issue.

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. (BZ#669440)

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

(BZ#632704)

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

(BZ#634225)

  • The clustat utility now reports the correct version. (BZ#654160)
  • The oracledb.sh agent now attempts to try the "shutdown immediate"

command instead of using the "shutdown abort" command. (BZ#633992)

  • The SAPInstance and SAPDatabase scripts now use proper directory name

quoting so they no longer collide with directory names like "/u".
(BZ#637154)

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

(BZ#592613)

  • The nfsclient resource agent now handles paths with trailing slashes

correctly. (BZ#592624)

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

(BZ#610483)

  • The /usr/share/cluster/fs.sh script no longer runs the "quotaoff" command

if quotas were not configured. (BZ#637678)

  • The "listen" line in the /etc/httpd/conf/httpd.conf file generated by the

Apache resource agent is now correct. (BZ#675739)

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

(BZ#637802)

  • The time required to stop an NFS resource when the server is unavailable

has been reduced. (BZ#678494)

  • When using exclusive prioritization, a higher priority service now

preempts a lower priority service after status check failures. (BZ#680256)

  • The postgres-8 resource agent now correctly detects failed start

operations. (BZ#663827)

  • The handling of reference counts passed by rgmanager to resource agents

now works properly, as expected. (BZ#692771)

As well, this update adds the following enhancements:

  • It is now possible to disable updates to static routes by the IP resource

agent. (BZ#620700)

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

(BZ#661893)

  • It is now possible to use the "clustat" command as a non-root user, so

long as that user is in the "root" group. (BZ#510300)

  • It is now possible to migrate virtual machines when central processing is

enabled. (BZ#525271)

  • The rgmanager init script will now delay after stopping services in order

to allow time for other nodes to restart them. (BZ#619468)

  • The handling of failed independent subtrees has been corrected.

(BZ#711521)

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