Summary
Red Hat Security Advisory: fence security, bug fix, and enhancement update

Notes

Topic
An updated fence package that fixes multiple security issues, several bugs, and adds two enhancements is now available for Red Hat Cluster Suite 4. The Red Hat Security Response Team has rated this update as having low security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Details
The fence package allows failed or unreachable nodes to be forcibly restarted and removed from a cluster. Insecure temporary file use flaws were found in fence_egenera, fence_apc, and fence_apc_snmp. A local attacker could use these flaws to overwrite an arbitrary file writable by the victim running those utilities via a symbolic link attack. (CVE-2008-4192, CVE-2008-4579) This update also fixes the following bugs: * fence_apc_snmp now waits for five seconds after fencing to properly get status. (BZ#494587) * The fence_drac5 help output now shows the proper commands. (BZ#498870) * fence_scsi_test.pl now verifies that sg_persist is in the path before running. (BZ#500172) * fence_drac5 is now more consistent with other agents and uses module_name instead of modulename. (BZ#500546) * fence_apc and fence_wti no longer fail with a pexpect exception. (BZ#501890, BZ#504589) * fence_wti no longer issues a traceback when an option is missing. (BZ#508258) * fence_sanbox2 is now able to properly obtain the status after fencing. (BZ#510279) * Fencing no longer fails if fence_wti is used without telnet. (BZ#510335) * fence_scsi get_scsi_devices no longer hangs with various devices. (BZ#545193) * fence_ilo no longer fails to reboot with ilo2 firmware 1.70. (BZ#545682) * Fixed an issue with fence_ilo not rebooting in some implementations. (BZ#576036) * fence_ilo no longer throws exceptions if the user does not have power privileges. (BZ#576178) As well, this update adds the following enhancements: * Support has been added for SSH-enabled RSA II fence devices. (BZ#476161) * The APC fence agent will now work with a non-root account. (BZ#491643) All fence users are advised to upgrade to this updated package, which corrects these issues and adds these enhancements.
