The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:1341 advisory.

    The Cluster Manager (cman) utility provides services for managing a Linux     cluster.

    Multiple insecure temporary file use flaws were found in fence_apc_snmp and     ccs_tool. A local attacker could use these flaws to overwrite an arbitrary     file writable by a victim running those utilities (typically root) with     the output of the utilities via a symbolic link attack. (CVE-2008-4579,     CVE-2008-6552)

    Bug fixes:

    * a buffer could overflow if cluster.conf had more than 52 entries per     block inside the <cman> block. The limit is now 1024.

    * the output of the group_tool dump subcommands were NULL padded.

    * using device= instead of label= no longer causes qdiskd to     incorrectly exit.

    * the IPMI fencing agent has been modified to time out after 10 seconds. It     is also now possible to specify a different timeout value with the '-t'     option.

    * the IPMI fencing agent now allows punctuation in passwords.

    * quickly starting and stopping the cman service no longer causes the     cluster membership to become inconsistent across the cluster.

    * an issue with lock syncing caused 'receive_own from' errors to be logged     to '/var/log/messages'.

    * an issue which caused gfs_controld to segfault when mounting hundreds of     file systems has been fixed.

    * the LPAR fencing agent now properly reports status when an LPAR is in     Open Firmware mode.

    * the LPAR fencing agent now works properly with systems using the     Integrated Virtualization Manager (IVM).

    * the APC SNMP fencing agent now properly recognizes outletStatusOn and     outletStatusOff return codes from the SNMP agent.

    * the WTI fencing agent can now connect to fencing devices with no     password.

    * the rps-10 fencing agent now properly performs a reboot when run with no     options.

    * the IPMI fencing agent now supports different cipher types with the '-C'     option.

    * qdisk now properly scans devices and partitions.

    * cman now checks to see if a new node has state to prevent killing the     first node during cluster setup.

    * 'service qdiskd start' now works properly.

    * the McData fence agent now works properly with the McData Sphereon 4500     Fabric Switch.

    * the Egenera fence agent can now specify an SSH login name.

    * the APC fence agent now works with non-admin accounts when using the     3.5.x firmware.

    * fence_xvmd now tries two methods to reboot a virtual machine.

    * connections to OpenAIS are now allowed from unprivileged CPG clients with     the user and group of 'ais'.

    * groupd no longer allows the default fence domain to be '0', which     previously caused rgmanager to hang. Now, rgmanager no longer hangs.

    * the RSA fence agent now supports SSH enabled RSA II devices.

    * the DRAC fence agent now works with the Integrated Dell Remote Access     Controller (iDRAC) on Dell PowerEdge M600 blade servers.

    * fixed a memory leak in cman.

    * qdisk now displays a warning if more than one label is found with the     same name.

    * the DRAC5 fencing agent now shows proper usage instructions for the '-D'     option.

    * cman no longer uses the wrong node name when getnameinfo() fails.

    * the SCSI fence agent now verifies that sg_persist is installed.

    * the DRAC5 fencing agent now properly handles modulename.

    * QDisk now logs warning messages if it appears its I/O to shared storage     is hung.

    * fence_apc no longer fails with a pexpect exception.

    * removing a node from the cluster using 'cman_tool leave remove' now     properly reduces the expected_votes and quorum.

    * a semaphore leak in cman has been fixed.

    * 'cman_tool nodes -F name' no longer segfaults when a node is out of     membership.

    Enhancements:

    * support for: ePowerSwitch 8+ and LPAR/HMC v3 devices, Cisco MDS 9124 and     MDS 9134 SAN switches, the virsh fencing agent, and broadcast communication     with cman.

    * fence_scsi limitations added to fence_scsi man page.

    Users of cman are advised to upgrade to these updated packages, which     resolve these issues and add these enhancements.

NOTE: openais and pexpect updates are required.

This update includes security fixes for: CVE-2008-4192 CVE-2008-4579 among many other upstream bug fixes.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote host is affected by the vulnerability described in GLSA-201009-09 (fence: Multiple symlink vulnerabilities)

    The fence_apc, fence_apc_snmp (CVE-2008-4579) and fence_manual     (CVE-2008-4580) programs contain symlink vulnerabilities.
  Impact :

    These vulnerabilities may allow arbitrary files to be overwritten with     root privileges.
  Workaround :

    There is no known workaround at this time.

Multiple insecure temporary file handling vulnerabilities were discovered in Red Hat Cluster. A local attacker could exploit these to overwrite arbitrary local files via symlinks. (CVE-2008-4192, CVE-2008-4579, CVE-2008-4580, CVE-2008-6552)

It was discovered that CMAN did not properly handle malformed configuration files. An attacker could cause a denial of service (via CPU consumption and memory corruption) in a node if the attacker were able to modify the cluster configuration for the node. (CVE-2008-6560).
