(RHSA-2010:0330) Moderate: GFS security and bug fix update

The Red Hat Global File System (GFS) allows a cluster of Linux servers to
share data in a common pool of storage.

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)

As well, these updated GFS packages are in sync with the latest kernel
(2.4.21-63.EL). The modules in earlier GFS packages fail to load because
they do not match the running kernel. It is possible to force-load the
modules; however, with this update, force-loading the modules is not
required. (BZ#525198)

Users are advised to upgrade to these latest GFS packages, which resolve
this issue and are updated for use with the 2.4.21-63.EL kernel.
