Test ID:1.3.6.1.4.1.25623.1.0.71934
Category:Red Hat Local Security Checks
Title:RedHat Security Advisory RHSA-2010:0521
Summary:NOSUMMARY
Description:Description:
The remote host is missing updates announced in
advisory RHSA-2010:0521.

The gfs-kmod packages contain modules that provide the ability to mount and
use GFS file systems.

A flaw was found in the gfs_lock() implementation. The GFS locking code
could skip the lock operation for files that have the S_ISGID bit
(set-group-ID on execution) in their mode set. A local, unprivileged user
on a system that has a GFS file system mounted could use this flaw to cause
a kernel panic. (CVE-2010-0727)

These updated gfs-kmod packages are in sync with the latest kernel
(2.6.18-164.19.1.el5). The modules in earlier gfs-kmod packages failed to
load because they did not match the running kernel. It was possible to
force-load the modules. With this update, however, users no longer need to.

Users are advised to upgrade to these latest gfs-kmod packages, updated for
use with the 2.6.18-164.19.1.el5 kernel, which contain a backported patch
to correct this issue.

Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date
