    Synopsis:          Important: kernel security update
    Advisory ID:       RHSA-2015:0009-01
    Product:           Red Hat Enterprise Linux
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2015-0009.html
    Issue date:        2015-01-05
    CVE Names:         CVE-2014-9322 
    =====================================================================
    
    1. Summary:
    
    Updated kernel packages that fix one security issue are now available for
    Red Hat Enterprise Linux 4 Extended Life Cycle Support.
    
    Red Hat Product Security has rated this update as having Important 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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux AS (v. 4 ELS) - i386, ia64, noarch, x86_64
    Red Hat Enterprise Linux ES (v. 4 ELS) - i386, noarch, x86_64
    
    3. Description:
    
    The kernel packages contain the Linux kernel, the core of any Linux
    operating system.
    
    * A flaw was found in the way the Linux kernel handled GS segment register
    base switching when recovering from a #SS (stack segment) fault on an
    erroneous return to user space. A local, unprivileged user could use this
    flaw to escalate their privileges on the system. (CVE-2014-9322, Important)
    
    Red Hat would like to thank Andy Lutomirski for reporting this issue.
    
    All kernel users are advised to upgrade to these updated packages, which
    contain a backported patch to correct this issue. The system must be
    rebooted for this update to take effect.
    
    4. Solution:
    
    Before applying this update, make sure all previously released errata
    relevant to your system have been applied.
    
    This update is available via the Red Hat Network. Details on how to use the
    Red Hat Network to apply this update are available at
    https://access.redhat.com/articles/11258
    
    To install kernel packages manually, use "rpm -ivh [package]". Do not use
    "rpm -Uvh" as that will remove the running kernel binaries from your
    system. You may use "rpm -e" to remove old kernels after determining that
    the new kernel functions properly on your system.
    
    5. Bugs fixed (https://bugzilla.redhat.com/):
    
    1172806 - CVE-2014-9322 kernel: x86: local privesc due to bad_iret and paranoid entry incompatibility
