Detailsinfo

A vulnerability, which was classified as problematic, has been found in MaraDNS 1.3.07.012/1.4.08. This issue affects an unknown code block. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. The summary by CVE is:

MaraDNS 1.3.07.12 and 1.4.08 computes hash values for DNS data without properly 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. NOTE: this issue exists because of an incomplete fix for CVE-2012-0024.

The weakness was disclosed 01/07/2012 (Website). The advisory is shared at samiam.org. The identification of this vulnerability is CVE-2011-5055 since 01/07/2012. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 73480 (MaraDNS < 1.3.07.14 / 1.4.x < 1.4.10 Hash Collision Form Parameter Remote DoS), which helps to determine the existence of the flaw in a target environment. It is assigned to the family DNS and running in the context r.

Upgrading eliminates this vulnerability. A possible mitigation has been published 6 days after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at Tenable (73480) and SecurityFocus (BID 51225†). The entry VDB-59899 is pretty similar. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
