Description
A flaw was found in the way BIND handled zero length resource data records.
A malicious owner of a DNS domain could use this flaw to create
specially-crafted DNS resource records that would cause a recursive
resolver or secondary server to crash or, possibly, disclose portions of
its memory. (CVE-2012-1667)
A flaw was found in the way BIND handled the updating of cached name server
(NS) resource records. A malicious owner of a DNS domain could use this
flaw to keep the domain resolvable by the BIND server even after the
delegation was removed from the parent DNS zone. With this update, BIND
limits the time-to-live of the replacement record to that of the
time-to-live of the record being replaced. (CVE-2012-1033)
