The remote host is missing an update for the 'opensm'
Linux Distribution Package(s) announced via the referenced advisory.
opensm on CentOS 6
Please install the updated Linux Distribution Packages.
Red Hat Enterprise Linux includes a collection of InfiniBand and iWARP
utilities, libraries and development Linux Distribution Packages for writing applications
that use Remote Direct Memory Access (RDMA) technology.
A denial of service flaw was found in the way ibacm managed reference
counts for multicast connections. An attacker could send specially-crafted
multicast packets that would cause the ibacm daemon to crash.
It was found that the ibacm daemon created some files with world-writable
permissions. A local attacker could use this flaw to overwrite the
contents of the ibacm.log or ibacm.port file, allowing them to mask
certain actions from the log or cause ibacm to run on a non-default port.
CVE-2012-4518 was discovered by Florian Weimer of the Red Hat Product
Security Team and Kurt Seifried of the Red Hat Security Response Team.
The InfiniBand/iWARP/RDMA stack components have been upgraded to more
recent upstream versions.
This update also fixes the following bugs:
* Previously, the 'ibnodes -h' command did not show a proper usage message.
With this update the problem is fixed and 'ibnodes -h' now shows the
correct usage message. (BZ#818606)
* Previously, the ibv_devinfo utility erroneously showed iWARP cxgb3
hardware's physical state as invalid even when the device was working. For
iWARP hardware, the phys_state field has no meaning. This update patches
the utility to not print out anything for this field when the hardware is
iWARP hardware. (BZ#822781)
* Prior to the release of Red Hat Enterprise Linux 6.3, the kernel created
the InfiniBand device files in the wrong place and a udev rules file was
used to force the devices to be created in the proper place. With the
update to 6.3, the kernel was fixed to create the InfiniBand device files
in the proper place, and so the udev rules file was removed as no longer
being necessary. However, a bug in the kernel device creation meant that,
although the devices were now being created in the right place, they had
incorrect permissions. Consequently, when users attempted to run an RDMA
application as a non-root user, the application failed to get the necessary
permissions to use the RDMA device and the application terminated. This
update puts a new udev rules file in place. It no longer attempts to create
the InfiniBand devices since they already exist, but it does correct the
device permissions on the files. (BZ#834428)
