CVE-2011-5055

Published Jan 8, 2012 maradns CWE-20

Overview

CVE-2011-5055 is a known-severity vulnerability affecting maradns maradns. It was published on January 8, 2012.

Technical Description

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.

Remediation

Check the references section for vendor advisories and patches from maradns. Update maradns to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
