Scientific Linux Security Update : GFS on SL3.x i386/x86_64

This script is Copyright (C) 2012 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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.
