Description :

The remote host is affected by the vulnerability described in GLSA-201209-04
(BIND: Multiple vulnerabilities)

Multiple vulnerabilities have been discovered in BIND:
Domain names are not properly revoked due to an error in the cache
update policy (CVE-2012-1033).
BIND accepts records with zero-length RDATA fields (CVE-2012-1667).
An assertion failure from the failing-query cache could occur when
DNSSEC validation is enabled (CVE-2012-3817).
A memory leak may occur under high TCP query loads (CVE-2012-3868).
An assertion error can occur when a query is performed for a record
with RDATA greater than 65535 bytes (CVE-2012-4244).

Impact :

A remote attacker may be able to cause a Denial of Service condition or
keep domain names resolvable after it has been deleted from registration.

Workaround :

There is no known workaround at this time.
