CVE-2011-5055
Last modified
CVE-2011-5055 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 1.58% chance of exploitation in the next 30 days.
