    Synopsis:          Important: bind97 security update
    Advisory ID:       RHSA-2012:1122-01
    Product:           Red Hat Enterprise Linux
    Advisory URL:      https://rhn.redhat.com/errata/RHSA-2012-1122.html
    Issue date:        2012-07-31
    CVE Names:         CVE-2012-3817 
    =====================================================================
    
    1. Summary:
    
    Updated bind97 packages that fix one security issue are now available for
    Red Hat Enterprise Linux 5.
    
    The Red Hat Security Response Team 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:
    
    RHEL Desktop Workstation (v. 5 client) - i386, x86_64
    Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
    
    3. Description:
    
    The Berkeley Internet Name Domain (BIND) is an implementation of the Domain
    Name System (DNS) protocols. BIND includes a DNS server (named); a resolver
    library (routines for applications to use when interfacing with DNS); and
    tools for verifying that the DNS server is operating correctly.
    
    An uninitialized data structure use flaw was found in BIND when DNSSEC
    validation was enabled. A remote attacker able to send a large number of
    queries to a DNSSEC validating BIND resolver could use this flaw to cause
    it to exit unexpectedly with an assertion failure. (CVE-2012-3817)
    
    Users of bind97 are advised to upgrade to these updated packages, which
    correct this issue. 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/knowledge/articles/11258
    
    5. Bugs fixed (http://bugzilla.redhat.com/):
    
    842897 - CVE-2012-3817 bind: heavy DNSSEC validation load can cause assertion failure
