    Package : bind9
    Vulnerability : denial of service
    Problem type : remote
    Debian-specific: no

    The BIND, a DNS server, contains a defect related to the processing of
    new DNSSEC DS records by the caching resolver, which may lead to name resolution failures in the delegated zone. If DNSSEC validation is
    enabled, this issue can make domains ending in .COM unavailable when
    the DS record for .COM is added to the DNS root zone on March 31st,
    2011. An unpatched server which is affected by this issue can be
    restarted, thus re-enabling resolution of .COM domains.

    Configurations not using DNSSEC validations are not affected by this
    usse.

    For the oldstable distribution (lenny), this problem has been fixed in
    version 1:9.6.ESV.R4+dfsg-0+lenny1.

    We recommend that you upgrade your bind9 packages.
