Описание
A flaw was found in Aardvark-dns, which is vulnerable to a Denial of Service attack due to the serial processing of TCP DNS queries. An attacker can exploit this flaw by keeping a TCP connection open indefinitely, causing the server to become unresponsive and resulting in other DNS queries timing out. This issue prevents legitimate users from accessing DNS services, thereby disrupting normal operations and causing service downtime.
Отчет
This vulnerability is classified as moderate severity because it affects the availability of the service rather than compromising data confidentiality or integrity. The CVSS score reflects its impact on system availability, as the DoS attack can lead to significant downtime and service disruption but does not involve unauthorized data access or code execution.
Меры по смягчению последствий
It is advised to upgrade aardvark-dns to version 1.12.1 or higher.
