Description Agostino Sarubbo gentoo-dev 2012-02-08 11:23:37 UTC
From secunia security advisory at $URL:

The vulnerability is caused due to an error within the cache update policy, which does not properly handle revoked domain names. This can be exploited to keep the domain name resolvable after being deleted from registration.

The vulnerability is reported in all 9.x versions.


Original Advisory
Comment 1 GLSAMaker/CVETool Bot gentoo-dev 2012-02-20 05:13:08 UTC
CVE-2012-1033 (
  The resolver in ISC BIND 9 through 9.8.1-P1 does not properly implement a
  cache update policy, which allows remote attackers to trigger continued
  resolvability of domain names that are no longer registered via an
  unspecified "Ghost Names exploit."
