    Synopsis
    ========
    
    Multiple vulnerabilities have been found in BIND, the worst of which
    could result in a Denial of Service condition.
    
    Background

    BIND (Berkeley Internet Name Domain) is a Name Server.
    
    Affected packages
    =================

    Description
    ===========
    
    Multiple vulnerabilities have been discovered in BIND. Please review
    the CVE identifiers referenced below for details.
    
    Impact
    ======
    
    BIND can improperly permit recursive query service to unauthorized
    clients possibly resulting in a Denial of Service condition or to be
    used in DNS reflection attacks.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All bind users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-dns/bind-9.12.1_p2-r1"
