Scientific Linux Security Update : cman on SL5.x i386/x86_64
medium Nessus Plugin ID 60650
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
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.
NOTE: openais and pexpect updates are required.
