CVE-2011-5056 is a vulnerability of currently unknown severity. The authoritative server in MaraDNS through 2.0.04 computes hash values for DNS data without restricting the ability to trigger hash collisions predictably, which might allow local users to cause a denial of service (CPU consumption) via crafted records in zone files, a different vulnerability than CVE-2012-0024.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
