The Cluster Manager 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 with the output of the utilities via a symbolic link attack. 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 . * 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 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.
