    It was discovered that BIND, an implementation of the DNS protocol, does not correctly process certain large RRSIG record sets in DNSSEC responses. The resulting assertion failure causes the name server process to crash, making name resolution unavailable. (CVE-2011-1910)

    Package        : bind9
    Vulnerability  : incorrect boundary condition
    Problem type   : remote
    Debian-specific: no
    CVE ID         : CVE-2011-1910
    
    It was discovered that BIND, an implementation of the DNS protocol,
    does not correctly process certain large RRSIG record sets in DNSSEC
    responses.  The resulting assertion failure causes the name server
    process to crash, making name resolution unavailable.  (CVE-2011-1910)
    
    In addition, this update fixes handling of certain signed/unsigned
    zone combinations when a DLV service is used.  Previously, data from
    certain affected zones could become unavailable from the resolver.
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 1:9.6.ESV.R4+dfsg-0+lenny2.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 1:9.7.3.dfsg-1~squeeze2.
    
    The testing distribution (wheezy) and the unstable distribution (sid)
    will be fixed soon.
    
    We recommend that you upgrade your bind9 packages.
