    Synopsis:          Moderate: bind97 security and bug fix update
    Advisory ID:       RHSA-2014:1244-01
    Product:           Red Hat Enterprise Linux
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1244.html
    Issue date:        2014-09-16
    CVE Names:         CVE-2014-0591 
    =====================================================================
    
    1. Summary:
    
    Updated bind97 packages that fix one security issue and one bug are now
    available for Red Hat Enterprise Linux 5.
    
    Red Hat Product Security 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.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
    Red Hat Enterprise Linux Desktop Workstation (v. 5 client) - i386, x86_64
    
    3. Description:
    
    The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
    Name System (DNS) protocols. It contains a DNS server (named), a resolver
    library with routines for applications to use when interfacing with DNS,
    and tools for verifying that the DNS server is operating correctly.
    These packages contain version 9.7 of the BIND suite.
    
    A denial of service flaw was found in the way BIND handled queries for
    NSEC3-signed zones. A remote attacker could use this flaw against an
    authoritative name server that served NCES3-signed zones by sending a
    specially crafted query, which, when processed, would cause named to crash.
    (CVE-2014-0591)
    
    Note: The CVE-2014-0591 issue does not directly affect the version of
    bind97 shipped in Red Hat Enterprise Linux 5. This issue is being addressed
    however to assure it is not introduced in future builds of bind97 (possibly
    built with a different compiler or C library optimization).
    
    This update also fixes the following bug:
    
    * Previously, the bind97 initscript did not check for the existence of the
    ROOTDIR variable when shutting down the named daemon. As a consequence,
    some parts of the file system that are mounted when using bind97 in a
    chroot environment were unmounted on daemon shut down, even if bind97 was
    not running in a chroot environment. With this update, the initscript has
    been fixed to check for the existence of the ROOTDIR variable when
    unmounting some parts of the file system on named daemon shut down. Now,
    when shutting down bind97 that is not running in a chroot environment, no
    parts of the file system are unmounted. (BZ#1059118)
    
    All bind97 users are advised to upgrade to these updated packages, which
    contain backported patches to correct these issues. After installing the
    update, the BIND daemon (named) will be restarted automatically.
    
    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
