Description:
A vulnerability has been reported in MaraDNS, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error within the handling of certain DNS packets. This can be exploited to cause a resource rotation by sending specially crafted DNS packets, which cause an authoritative CNAME record to not resolve, resulting in a DoS.
The vulnerability is reported in version 1.0.x prior to 1.0.41, 1.2.x prior to 1.2.12.08, and 1.3.x prior to 1.3.07.04.
