Descriptions

A flaw was found in Aardvark-dns versions 1.12.0 and 1.12.1. They contain a denial of service vulnerability due to serial processing of TCP DNS queries. This flaw allows a malicious client to keep a TCP connection open indefinitely, causing other DNS queries to time out and resulting in a denial of service for all other containers using aardvark-dns.

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.

An update for aardvark-dns is now available for Red Hat Enterprise Linux 9. Issues addressed include a denial of service vulnerability.
