CVE-2011-5055 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:22.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream maradns package and not the maradns package as distributed by Ubuntu.
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.
