Updated gfs-kmod packages that fix one security issue are now available for Red Hat Enterprise Linux 5.4 Extended Update Support, kernel release 2.6.18-164.19.1.el5.
The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
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.
