Red Hat Security Advisory

Synopsis: Low: cman security, bug fix, and enhancement update
Advisory ID: RHSA-2009:1341-02
Product: Red Hat Enterprise Linux
Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1341.html
Issue date: 2009-09-02
Keywords: cman
CVE Names: CVE-2008-4579 CVE-2008-6552
=====================================================================

1. Summary:

Updated cman packages that fix several security issues, various bugs, and
add enhancements are now available for Red Hat Enterprise Linux 5.

This update has been rated as having low security impact by the Red Hat
Security Response Team.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

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 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.
