    3. Description:
    
    The GNU Bourne Again shell (Bash) is a shell and command language
    interpreter compatible with the Bourne shell (sh). Bash is the default
    shell for Red Hat Enterprise Linux.
    
    It was found that the fix for CVE-2014-6271 was incomplete, and Bash still
    allowed certain characters to be injected into other environments via
    specially crafted environment variables. An attacker could potentially use
    this flaw to override or bypass environment restrictions to execute shell
    commands. Certain services and applications allow remote unauthenticated
    attackers to provide environment variables, allowing them to exploit this
    issue. (CVE-2014-7169)
    
    Applications which directly create bash functions as environment variables
    need to be made aware of changes to the way names are handled by this
    update. For more information see the Knowledgebase article at
    https://access.redhat.com/articles/1200223
    
    Note: Docker users are advised to use "yum update" within their containers,
    and to commit the resulting changes.
    
    For additional information on CVE-2014-6271 and CVE-2014-7169, refer to the
    aforementioned Knowledgebase article.
    
    All bash users are advised to upgrade to these updated packages, which
    contain a backported patch to correct this issue.
    
    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
    
    5. Bugs fixed (https://bugzilla.redhat.com/):
    
    1146319 - CVE-2014-7169 bash: code execution via specially-crafted environment (Incomplete fix for CVE-2014-6271)
