Vulnerability Summary for CVE-2012-1033

Original release date: 02/08/2012
Last revised: 01/03/2013


The resolver in ISC BIND 9 through 9.8.1-P1 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "ghost domain names" attack.


CVSS Severity (version 2.0):
CVSS v2 Base Score: 5.0 (MEDIUM) (AV:N/AC:L/Au:N/C:N/I:P/A:N) (legend)
Impact Subscore: 2.9
Exploitability Subscore: 10.0
CVSS Version 2 Metrics:
Access Vector: Network exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows unauthorized modification


Per: https://www.isc.org/software/bind/advisories/cve-2012-1033 'Solution: On further review, ISC has determined that this is not an issue which needs an immediate patch. The issue is being reviewed at the protocol level and will be addressed there. Implementing DNSSEC is the safest mitigation measure.'
