| Name | CVE-2012-0024 |
| Description | MaraDNS before 1.3.07.12 and 1.4.x before 1.4.08 computes hash values for DNS data without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted queries with the Recursion Desired (RD) bit set. |

Notes
[squeeze] - maradns <no-dsa> (Minor issue)
[lenny] - maradns <no-dsa> (Minor issue)
a DoS that requires being able to do recursive queries. Allowing recursive queries to the general public is already a security issue to begin with, so this issue can better be addressed in a point update.
