Last modified Jun 16, 2026

CVE-2012-0024 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 2.89% chance of exploitation in the next 30 days.
