    It was discovered that Unbound, a recursive DNS resolver, would crash
    when processing certain malformed DNS responses from authoritative DNS
    servers, leading to denial of service.

    For the oldstable distribution (lenny), these problems have been fixed in
    version 1.4.6-1~lenny2.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 1.4.6-1+squeeze2.
    
    For the testing distribution (wheezy) and the unstable distribution
    (sid), these problems have been fixed in version 1.4.14-1.
    
    We recommend that you upgrade your unbound packages.
