    Package        : unbound
    Vulnerability  : design flaw
    Problem type   : remote
    Debian-specific: no
    CVE ID         : CVE-2009-4008
    
    It was discovered that Unbound, a caching DNS resolver, ceases to
    provide answers for zones signed using DNSSEC after it has processed a
    crafted query.  (CVE-2009-4008)
    
    In addition, this update improves the level of DNSSEC support in the
    lenny version of Unbound so that it is possible for system
    administrators to configure the trust anchor for the root zone.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 1.4.6-1~lenny1.
    
    For the other distributions (squeeze, wheezy, sid), this problem has
    been fixed in version 1.4.4-1.
    
    We recommend that you upgrade your unbound packages.
