Red Hat Security Advisory
Synopsis: Low: rgmanager security, bug fix, and enhancement update
Advisory ID: RHSA-2009:1339-02
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1339.html
Issue date: 2009-09-02
CVE Names: CVE-2008-6552
An updated rgmanager package that fixes multiple security issues, various
bugs, and adds enhancements is now available for Red Hat Enterprise Linux
This update has been rated as having low security impact by the Red Hat
Security Response Team.
2. Relevant releases/architectures:
RHEL Clustering (v. 5 server) - i386, ia64, ppc, x86_64
The rgmanager package contains the Red Hat Resource Group Manager, which
provides high availability for critical server applications in the event of
Multiple insecure temporary file use flaws were discovered in rgmanager and
various resource scripts run by rgmanager. A local attacker could use these
flaws to overwrite an arbitrary file writable by the rgmanager process
(i.e. user root) with the output of rgmanager or a resource agent via a
symbolic link attack. (CVE-2008-6552)
This update also fixes the following bugs:
* clulog now accepts '-' as the first character in messages.
* if expire_time is 0, max_restarts is no longer ignored.
* the SAP resource agents included in the rgmanager package shipped with
Red Hat Enterprise Linux 5.3 were outdated. This update includes the most
recent SAP resource agents and, consequently, improves SAP failover
* empty PID files no longer cause resource start failures.
* recovery policy of type 'restart' now works properly when using a
resource based on ra-skelet.sh.
* samba.sh has been updated to kill the PID listed in the proper PID file.
* handling of the '-F' option has been improved to fix issues causing
rgmanager to crash if no members of a restricted failover domain were
* the number of simultaneous status checks can now be limited to prevent
* forking and cloning during status checks has been optimized to reduce
* rg_test no longer hangs when run with large cluster configuration files.
* when rgmanager is used with a restricted failover domain it will no
longer occasionally segfault when some nodes are offline during a failover
* virtual machine guests no longer restart after a cluster.conf update.
* nfsclient.sh no longer leaves temporary files after running.
* extra checks from the Oracle agents have been removed.
* vm.sh now uses libvirt.
* users can now define an explicit service processing order when
central_processing is enabled.
* virtual machine guests can no longer start on 2 nodes at the same time.
* in some cases a successfully migrated virtual machine guest could restart
when the cluster.conf file was updated.
* incorrect reporting of a service being started when it was not started
has been addressed.
As well, this update adds the following enhancements:
* a startup_wait option has been added to the MySQL resource agent.
* services can now be prioritized.
* rgmanager now checks to see if it has been killed by the OOM killer and
if so, reboots the node.
Users of rgmanager are advised to upgrade to this updated package, which
resolves these issues and adds these enhancements.
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
