Insight

Insight

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 d ...
